When any one of the spools in a valve bank is shifted it blocks off the open center passage. The oil then flows into the parallel circuit core making oil available to all spools. If more than one spool is fully shifted then oil will go to the section with the lowest pressure requirements. It is possible, however, to meter flow to the spool with the least load and power two unequal loads. The schematic below shows a three section parallel circuit stack valve. THE POWER CORE OF LL SECTIONS THE VLVE STCK RE CONNECTED TOGETHER Y THE PRLLEL CORE THT RUNS THROUGH THE LENGTH OF THE VLVE Tandem circuit construction is also referred to as priority circuit. When the spool of a section is shifted, oil is cut off to all downstream sections. Thus the section nearest to the inlet has priority over the other sections in the valve bank. If more than one spool is fully shifted all the oil will go to the section nearest to the inlet. Metering the up stream section will allow two sections to operate at the same time. The schematic below shows a three section tandem circuit stack valve. THE POWER CORE OF WORK SECTION IS FED Y THE OIL EXITG THE OPEN CENTER OF THE DJCENT UPSTREM WORK SECTION Parallel and tandem circuit work sections can be combined in the same valve bank. elow the 1st and last sections are parallel and the 2nd is tandem. The 1st parallel section has priority over the other two. The 2nd and 3rd sections are in parallel with each other. If the spool of the 1st section is shifted it will cut off oil to the other two. If the spools of the 2nd and 3rd section are both shifted oil will go to the one with the least resistance. It should be noted that it is the section just prior to the tandem section that has priority, not the tandem section. Further if a parallel section is placed just after a tandem, the two sections will be in a parallel. 20P PRLLEL WORK SECTIONS 20T TNDEM WORK SECTION LOD CHECK OPEN CENTER PPLICTIONS CLOSED CENTER PPLICTIONS Each work port of the Series 20 stack valve has a separate load check. The load check prevents the fall of a cylinder as the spool is shifted. It also prevents the back-flow of oil from the work port to the inlet. The pump must build up enough pressure to overcome the pressure on the work port caused by the weight of the load before the cylinder can move. PLESE NOTE that the load check has nothing to do with how well the valve will hold up a cylinder with the spool in neutral. The load check is functional only when the spool is shifted. The standard Series 20 stack valve is open center. When the spools are in neutral hydraulic oil is directed from the inlet to the outlet (or power beyond) through the open center core. Moving one or more spools closes off the open center core and directs oil to the work ports. Open center systems most often contain fixed displacement pumps like The Prince SP series gear pumps. PLESE NOTE that the maximum pressure in an open center system is controlled by a relief valve. The Series 20 inlet sections are available with a built in inlet relief for this purpose. The Series 20 stack valve can be converted to closed center by adding the closed center plug to the outlet section. This blocks off the open center core when the spools are in neutral. These systems often use a variable displacement pressure compensated pump that limits the maximum pressure. When spools are in neutral system pressure is maintained at inlet of the valve. relief is normally not required or must be set at a higher pressure than the pump compensator. PLESE NOTE that this closed center option does not provide for the drain off of standby spool leakage. This can allow a very small amount of oil to enter the work ports when in neutral. CTV O.E.M.

O-RG GROOVES WORK PORT DJUSTLE RELIEF SHOWN SHIM DJUSTLE RELIEF SHOWN HNDLE OPTION 7 SHOWN HERE SPOOL TTCHMENT OPTION SHOWN HERE MODEL 20S SERIES CIRCUIT series circuit valve is most commonly used to control more than one hydraulic component simultaneously. The entire circuit flow is available to each valve section that is actuated. In a two spool series valve with both spools actuated, the oil flows from the inlet to the work port of the first section. The return flow of the first section is directed to the open center core of the second section. (In a parallel valve the return oil from the work port is directed to the tank core.) From the open center core of the second section, the oil flows to the work port with the return oil going to the outlet. In a series circuit valve, the summation of the pressures required for each work section will equal the total pressure required for the circuit. The total pressure required must not exceed the system relief setting for the pump pressure rating. It is not required to have a Series 20 series section as the last section, unless series flow is required to a downstream valve. In this application, a power beyond plug must be used in the outlet section. COMED SERIES/ PRLLEL CIRCUITS The Series 20 series sections may be stacked with 20P parallel circuit valve sections. When using a series section, the immediate downstream section needs to be a series, tandem, or outlet section. 20P sections can be either in front of the Series 20 series sections or behind a combination of series and tandem sections. For solenoid operation with series sections and a 20U utility section, there needs to be a Series 20 tandem section with pilot passageways between the series section and the utility section. In the valve assembly shown below, the first and fourth sections are parallel. The second section is series, the third section is tandem. The first parallel section has priority over all downstream valves. When the spool of the first parallel section is actuated, the return oil from the work port is directed to the tank core, thus oil flow to downstream sections is cut off. The second and third sections are in series with each other as well as the second and fourth sections. The third and fourth sections are in parallel with each other. CLOSED CENTER PPLICTIONS The Series 20 Series circuit valve sections cannot be used in a closed center valve assembly.

The valve is a parallel circuit, closed center design, where flow does not flow through the valve when the spools are centered. load sense signal line must be connected to the load sense port on the pump and to the load sense port on the 20LE outlet section of the valve. The pressure-flow compensator portion of a load sense pump will maintain (within its flow and pressure limitations) an output pressure equal to the pressure at the load sense port plus the load sense differential pressure. The differential pressure is typically between 150 and 350 psi. The valve is designed so that when a spool is shifted, the pressure at the out flow work port is presented to the valves load sense port. The valve incorporates logic and load sense check valves so that when multiple spools are shifted, the highest pressure of any of the work ports is directed to the load sense port. load sense line bleed orifice needs to be present in either the Prince load sense outlet or the load sense pump controls. The bleed orifice will prevent high pressure from being trapped in the load sense line and sending false signals to the pump. There are a number of benefits to load sense systems, one of the primary ones being in the metering of the flow to the work ports. Metering is typically accomplished when the flow passes through metering notches in the spool. In a load sense valve, the pressure that drives the flow through the notches is typically limited to the relatively low and nearly constant differential pressure. This relatively low differential pressure makes the notches more effective and gives more resolution in regard to spool travel versus flow out of the work port. lso, this resolution remains relatively the same regardless of the pressure required at the work port. The metering notches in the Prince load sense valve have been optimized to give excellent metering characteristics over an extended portion of the spool travel and over the full flow rating of the valve. The internal lands of the casting have also been machined to give repeatable, precise control to the metering characteristics. nother benefit to load sense valves is that, in the minimum flow standby mode, the pump only has to generate the rather low differential pressure thus saving energy as compared to typical open center or standard closed center systems. The Series 20LPC load sense pressure compensated valve incorporates a pressure compensator upstream to the metering notches on the spool ( pre-comp ). With either a fully shifted or partially shifted spool, work port flow will remain constant regardless of changing load pressure requirements. Pressure compensated sections are particularly useful in applications where the metering of flow, with varying pressure and flow conditions is required. The 20LPC sections have flow rated spools that determine the maximum flow from the individual work section. For instance the maximum flow from a work sections with a J10 spool is 10 gpm. Metering notches extend to the full travel of the spool. The lower flow spools will provide increased flow vs. spool travel resolution. With parallel circuitry, multiple sections can be used simultaneously to meter flow. If the sum of the flow rating of the shifted spools is less than the flow rating of the pump, all sections will receive flow. If the call for flow based on spool position from all work sections calls for more flow than the output of the pump, there may be some division of flow based on the section with the lowest pressure demand. The 20LPC is an optimal choice for proportional solenoid operation. It provides the greatest resolution of all the Prince proportional solenoid valves.

When all spools are centered, the inlet allows the pump flow to be diverted to tank at relatively low pressure. 3. When a spool is shifted, the compensator directs the flow to the work port at a flow and pressure relative to the work port/load sense pressure. The inlet retains the enhanced metering control of the load sense work sections. 4. For the 20ILF inlet, the 150 psi compensator is standard. It is typically used with flows up to approximately 25 gpm. For lower flows, a 90 psi compensator can be used. For higher flows, a 230 psi compensator can be used. For the 20ILFS inlet, a 230 T TNK PILOT LE LOD CHECK CORE TNK CORE LOD SENSE LE psi compensator is standard. In the 20ILFS, the compensator generates pilot pressure to initiate a spool shift when a solenoid is energized. Load induced pressure is required to complete and then maintain the spool shift. 5. For the 20ILFS, the flow to the solenoid cartridges is filtered through a 5 µ replaceable cartridge pressure filter. Only the pilot flow is filtered thus providing a long filter life. 6. Series 20 load sense outlet (20LEx1 for the 20ILF or a 20LEx3 for the 20ILFS) must be used in the stack valve assembly. 7. The load sense port on the outlet needs to be plugged with a steel plug. There is no external load sense line. 8. The 20ILFS requires a tie rod kit for one extra section.

18 JOYSTICK HNDLES FOR SERIES 20 This is a special handle for the SERIES 20 stack valve that allows the spools of two adjacent sections to be operated by one common handle. The spools can be operated independently or simultaneously depending on handle movement. The option is typically used on spring center to neutral sections. Normally, the handle is installed at the factory on sections ordered with handle option 7. However, the handle can also be installed in the field on valves originally equipped with standard handles (handle options 1 through 4). This drawing shows two joysticks with offset handles installed on a six section valve. typical handle to spool movement pattern is shown. Different patterns are also available. The Joystick handle can be used with standard three position spools or with four position float spools. If work port reliefs are required on the joystick end of a section, the relief cartridges must be the shim adjustable type. When two joysticks are installed on the same valve assembly, it is recommended that there be two standard section between them to prevent handle interference. When ordering a valve assembly, please refer to the following part numbers and indicate which sections the handle is to be installed on. The part numbers refer to the complete joystick assembly required to control two valve sections. Use the same part numbers to order kits for field installation.

The solenoid operated sections contain two, 3 way-2 position screw in style cartridge valves. The screw in cartridges provide a robust platform for the higher tank pressures often seen in mobile applications. Prince solenoid operated valves are pilot operated valves where pilot pressure is used to shift the spool. Depending on the model, the pilot pressure will be applied either directly to the end of the spool or to a piston that is connected to the spool. When both solenoids are de-energized, both spool end cavities or piston cavities are connected to tank. When the solenoid is energized, pilot pressure is applied to the end of the spool/piston, causing the spool to shift, against spring bias, and allow flow to the work port. Energizing the solenoid causes similar action on the end. Internal pilot passageways convey pilot pressure to the solenoid actuators. Pilot pressure is typically supplied by a utility section, but in the case of load sense sections or closed center assemblies, it can also be provided by an inlet manifold, which can be provided with filtered pilot flow. If a utility section is used, it must be installed between the last work section and the outlet cover. The utility section, or inlet manifold, limit the pilot pressure to approximately 350 psi. For an open center system, a pressure build up cartridge is needed in the utility section. The pressure build up section provides pilot pressure to initiate the spool shift. minimum of approximately 300 psi load induced pressure is required to complete the spool shift and hold the spool in the shifted position. For over center or light load applications a restrictor installed in the work port line may be required. Manual sections used in the same assembly with solenoid sections must either be upstream of solenoid sections or be custom sections machined with pilot passage ways in an assembly using a utility section. In assemblies with an inlet manifold, both solenoid and manual sections can be in the same assembly but, manual sections may have to be machined with pilot pass through passageways. For solenoid operated series sections, a tandem section with pilot pass through passageways must be between the series section and the utility section. Consult your sales representative for your application. Prince solenoid operators are offered in both a divided design (a solenoid on each end of the section) and a combined design (both solenoids on the end opposite the handle). We also currently offer models in both 10 thread size and 8 thread size solenoid cartridges. The 8 thread size offers a more compact assembly and a more economical choice as compared to a 10 thread size. V18 O.E.M.

24 SERIES 20 PROPORTIONL WORK SECTIONS In the Series 20 proportional work sections, varying pilot pressure is applied to the end of the spools to shift the spool against spring bias. Proportional pressure reducing cartridges are used to vary the pressure on the spools. s the current through the cartridge coil increases, the amount of the available pilot pressure applied to the ends of the spools also, proportionally increases. There will be a threshold pressure/current (dead band) to overcome the initial spring centering force and initial land coverage. Once this pressure/current has been exceeded, increasing the current through the coil will increase the flow from the work ports. Current to the coils is typically provided by a PWM current control module and a joystick or other input device. The coils require a maximum current of approximately 1300 m (@ 12 volts), and for reduced hysteresis, a dither frequency of approximately 100 Hz and a dither amplitude of 50 to 100 m. The controller should have adjustable minimum current and maximum current settings to minimize the dead band before work port flow starts and to maximize the control resolution. See page V38.6 for examples of control module and joystick components. The proportional work sections require pilot pressure to shift the spools. pproximately 325 psi pilot pressure will fully shift the spool in Prince proportional sections. With open center valve assemblies, the pilot pressure is typically supplied by a compensator inlet (20IC). The compensator inlets will provide adequate pilot pressure regardless of the load induced pressure. On load sense or load sense pressure comp systems used with a fixed displacement pump, a 20ILFS65370 inlet will provide pilot pressure. For load sense and load sense pressure comp systems used with a load sense pump, the standby pressure setting should be approximately 325 psi or more to provide for completely shifting the spool. Prince offers three basic proportional families. The first is open center proportional (based on the 20P family). The open center family, which is typically used with a fixed displacement (gear) pump is the least expensive of the three families. The open center family will provide controlled starts and stops of the work port flow, however, the metering band is not as wide as the other proportional families. The flow rate is also somewhat pressure dependent. The second family is load sense proportional and is based on the 20LP family. The load sense proportional has a wider metering band and the flow is not pressure dependent. The third family, based on the 20LPC family, is load sense pressure comp proportional. The load sense pressure comp family has the widest metering band, giving the most control and resolution. The load sense pressure comp family also has flow rated spools, providing for high resolution and control even for a few gpm with the 5 gpm spool. Using current minimum and current maximum settings on the controller will enhance the control in all three families.

35 PRLLEL CIRCUIT SVW, SVM, SVF, SVH, SVR, SVG ND SVL WORK SECTIONS Parallel circuit sections are by far the most common. The SVW, SVM, SVF, SVH, SVR, SVG and SVL are all of parallel circuit construction. They can be combined together in any order in an assembly. When any one of the spools is shifted, it blocks off the open center passage through the valve. The oil then flows into the parallel circuit core making oil available to all spools. If more than one spool is fully shifted, the oil will go to the spool with the lowest pressure requirements. However, it is possible to meter the flow to the spool with the least load and provide flow to two unequal loads. ENHNCED METERG SECTIONS The SVM, SVF, SVR and SVG sections have metering notches machined into the spool to allow for better feathering of a load. The spool travel for these sections is also a little longer at.281 vs..250 for the standard sections. In addition to the metering notches in the spool, the lands in the SVF and SVG bodies have been machined to give more precise control over the flow. The metering notches in the SVF and SVG have been optimized for flows of 10 gpm or less. For enhanced metering on higher flows, it is recommended that the SVM or SVR be used. LOCK SECTIONS The SVL section combines both a 4-way directional valve and a double pilot operated check valve. This provides very low leakage when the spool is in neutral. When the spool is shifted, oil is directed through a work port check to the cylinder. Pressure on the work port applies pressure to the shuttle spool, opening the opposite check valve and allowing oil to return into the valve. Depending on load pressures, the metering of the spool may be affected. In some cases a one way restrictor in a work port may be beneficial. SERIES CIRCUIT SVS WORK SECTIONS OPEN CENTER PSSGE LOD CHECK PRLLEL CIRCUIT CORE CONVERSION PLUG series circuit valve is most commonly used to control more than one hydraulic component simultaneously. The entire circuit flow is available to each valve section that is actuated. In a two spool series valve with both spools actuated, the oil flows from the inlet to the work port of the first section. The return flow of the first section is directed to the open center core of the second section. TNK RETURN TNK RETURN (In a parallel valve the return oil from the work port is directed to PORT PORT the tank core.) From the open center core of the second section, PORT PORT the oil flows to the work port with the return oil going to the outlet. In a series circuit valve, the summation of the pressures required for each work section will equal the total pressure required for the circuit. The total pressure required must not exceed the system relief setting or the pump pressure rating. It is not required to have a SV Series section as the last section, unless series flow is required to a downstream valve. In this application, a power beyond plug must be used in the outlet section. COMED SERIES / PRLLEL CIRCUITS SERIES SECTION SERIES SECTION The SV Series circuit valve sections may be stacked with SV parallel circuit valve sections. This allows both series and parallel control in the same valve assembly. In the valve assembly shown below, the first, third and fourth sections are parallel. The second section is series. The first parallel section has priority over all downstream valves. When the spool of the first parallel section is actuated, the return oil from the work port is directed to the tank core, thus oil flow to downstream sections is cut off. The second and third sections are in series with each other as is the second and fourth sections. The third and fourth sections are in parallel with each other. SERIES MOTOR SPOOL The SV Series Motor Spool provides control of reversible hydraulic motors. oth work ports are connected to the open center core in the neutral position. It should be noted that in the neutral position, the work ports will be equally pressurized to the same pressure that is required TNK RETURN TNK RETURN TNK RETURN TNK RETURN of any downstream valve sections and that a work port PORT PORT PORT PORT relief in the section will also limit the pressure of any PORT PORT PORT other sections in the valve. The series motor spool should PORT not be used to control a hydraulic cylinder as unwanted cylinder drift may occur in the neutral position. CLOSED CENTER PPLICTIONS The SV Series Circuit Valve sections cannot be used in a closed center valve assembly. PRLLEL SECTION SERIES SECTION PRLLEL SECTION PRLLEL SECTION P T CTV O.E.M.

41 SV (8 SERIES) SOLENOID OR MNUL WORK SECTIONS (OTH SOLENOIDS ON ONE END) DESCRIPTION OF OPERTION The Type -C SV Solenoid Work Section allows remote electrical on-off or manual control. The -C sections are 8 series work sections which use screw in cartridges with a #8 thread size. The screw in cartridges provide a robust platform for the higher tank pressures often seen in mobile applications and the #8 size allows for a more compact section size. Cartridges and coils on the 8 series are not interchangeable with the Prince 10 series solenoid sections or sections manufactured prior to November ny of the standard -S, -T, -C or -D style Prince SV solenoid operated work sections may be used in any combination within a stack valve assembly. The Type -C SV Solenoid Section contains two 3-way 2-position, #8 solenoid cartridge valves and a pilot operated piston attached to the main control spool. When both solenoids are de-energized, both sides of the pilot piston are open to tank pressure and the spool remains spring centered. When solenoid is energized, pilot pressure is applied to one side of the pilot piston, causing the spool to shift from the neutral position and direct flow to work port. When solenoid is energized, pilot pressure is applied to the other side of the pilot piston, causing the spool to shift and direct flow to work port. n optional manual override feature is available for the solenoid cartridges. Internal pilot lines provide pilot pressure to the solenoid actuator. Pilot pressure is generated by a Pressure uild-up Valve that is installed in the standard outlet section. Two versions of the pressure build-up valve are offered, the open center pressure build-up valve and power beyond pressure build-up valve. oth versions supply PSI pilot pressure to the solenoid actuator. closed center assembly does not require a pressure build-up valve. For an open center system, the pilot pressure can also be provided by an in inlet manifold, which can provide filtered pilot flow.

47 SV SOLENOID OPERTED WORK SECTION - PPLICTION FORMTION For over center or light load applications if the required work port load pressure drops below 200 PSI, the pilot pressure to the spool will drop to the same pressure causing the spring to move the control spool back towards the neutral position. The spool will end up in an intermediate position between neutral and fully shifted. restrictor installed in the work port or line may be required for this type of application. For closed center applications the Pressure uild-up Valve is not required. However, a system pressure of 200 PSI must be maintained in the closed center position to actuate the valve properly. Proper operation of the solenoid actuators requires a pressure differential of PSI above tank pressure. The maximum tank port pressure should not exceed 150 PSI. On C and S solenoid sections, excessive tank pressure will increase Seal Drag and may prohibit, the spool from shifting. The solenoid operated SV section may be converted to accept an external hydraulic pilot supply to the solenoid actuators. Please consult a Sales Representative for more information.

48 SV PROPORTIONL WORK SECTIONS In the SV proportional work sections, varying pilot pressure is applied to the end of the spools to shift the spool against spring bias. Proportional pressure reducing cartridges are used to vary the pressure on the spools. s the current through the cartridge coil increases, the amount of the available pilot pressure applied to the ends of the spools also, proportionally increases. There will be a threshold pressure/current (dead band) to overcome the initial spring centering force and initial land coverage. Once this pressure/current has been exceeded, increasing the current through the coil will increase the flow from the work ports. Current to the coils is typically provided by a PWM current control module and a joystick or other input device. The coils require a maximum current of approximately 1300 m (@ 12 volts), and for reduced hysteresis, a dither frequency of approximately 100 Hz and a dither amplitude of 50 to 100 m. The controller should have adjustable minimum current and maximum current settings to minimize the dead band before work port flow starts and to maximize the control resolution. See page V38.6 for examples of control module and joystick components. The proportional work sections require pilot pressure to shift the spools. pproximately 325 psi pilot pressure will fully shift the spool in Prince proportional sections. With open center valve assemblies, the pilot pressure is typically supplied by a compensator inlet (SVIC). The SV proportional work sections are open center sections based on the SVM family. The open center sections, which are typically used with a fixed displacement (gear) pump, provide for a cost effective circuit. The open center sections will provide controlled starts and stops of the work port flow, however, the metering band is not as wide as the other proportional families and metering is somewhat pressure dependent. Using current minimum and current maximum settings on the controller will enhance the metering control.

Each spool has a separate load check. The load check will prevent the fall of a cylinder as the spool is shifted. It also prevents the back-flow of oil from the work port to the inlet. s shown below the pump must build up enough pressure to overcome the pressure on the work port caused by the weight of the load before the cylinder can move.

WORK PORT "" SPOOL SHIFTED FULLY "OUT" SPOOL SHIFTED FULLY "OUT" OPEN CENTER PPLICTIONS: The Standard RD-5000 Series Valves are open center type valves. For open center valves the hydraulic oil is directed from the inlet to the outlet, or power beyond, through the open center passage when the spools are in neutral. Moving one or more spools closes off the open center passage and directs oil to the work ports. Open center systems most often contain fixed displacement pumps. The PMC hydraulic PTO pumps are fixed displacement gear pumps. The maximum pressure in an open center system is controlled by a relief valve. The RD-5000 series valves have a built in relief valve for this purpose. RD-5000 Series spool options, C, E and G are all open center spools when used with power beyond options,, C and F. CLOSED CENTER PPLICTIONS: RD-5000 Series Valves are available as closed center type valves. For closed center valves the oil through the open center passage is blocked when the spools are in neutral. Closed center systems often use a variable displacement pressure compensated pump. When this type of pump is used in a closed center system the system pressure is controlled by the pressure compensator. When the spools of RD-5000 series valve are in neutral, system pressure is maintained at the inlet of the valve. For this reason a relief is normally not required or must be set at a higher pressure than the pump compensator. RD-5000 Series spool options C, E and G are converted to closed center by installing a closed center conversion plug, power beyond option D. PLESE NOTE that this closed center option does not provide for the drain off of standby spool leakage. This can allow a very small amount of oil to enter the work ports when in neutral. CTV O.E.M.

58 3 WY 3 POSITION OPEN CENTER OPTION This spool option is used to control a single acting cylinder or a unidirectional motor. In neutral the work port is blocked and oil goes through the open center passage to the next spool of a multi-spool valve or the power beyond of a single spool valve. The port is plugged for this option. 4 WY 3 POSITION TNDEM CENTER OPTION C This spool option is used to control a double acting cylinder or a reversible motor. In neutral both of the work ports are blocked and oil goes through the open center passage to the next spool of a multi-spool valve or the power beyond of a single spool valve. This is the most popular spool option and is used on most Prince standard valves. 4 WY 3 POSITION CLOSED CENTER This spool option is similar to spool option C above except in neutral the open center passage is blocked. This function is achieved by using spool option C with a closed center conversion plug (Power beyond option D). 3 POSITION SPRG CENTER TO NEUTRL OPTION This option has 3 positions and a spring that returns the spool to neutral when the handle is released. This option is considered standard on many Prince valve models This option can be converted in the field to 3 position detent by ordering Kit It can be converted to friction detent by ordering Kit POSITION DETENT OPTION This option provides three detented positions. The spool will remain in any of the three positions in which it is manually placed. No centering spring is provided. Note: This option does not positively lock the spool in place. Excessive vibration or shock loads (4) may affect operation This option can be converted in the field to spring (4) center by ordering Kit It can be converted to friction detent by ordering Kit FRICTION DETENT OPTION C This option provides for a detent in the neutral position only. s the spool is manually moved away from the (4) neutral position it will be held in place by the friction of the detent balls on the detent sleeve. Note: ecause the spool is held in place by friction only, (4) excessive (4) (4) vibration may cause spool to move when not in the neutral detented position (4) This option can be converted in the field to spring center by ordering Kit and to 3 position detent by ordering Kit POSITION SPRG CENTER TO NEUTRL DETENT SPOOL FOR (2) FLOT POSITION OPTION G (2) This attachment is used with spool option G.

RD SPOOL SPECIL PPLICTION VLVE UTO-CYCLE TWO SPOOL VLVE This valve is a modified RD-5200 two spool valve that can be used to automatically cycle a hydraulic cylinder. The spools and the valve body have been modified to provide this function. oth spools have the pressure release detent spool attachment. The valve is shown connected to a cylinder in the sketch below. The port is connected to the base of the cylinder. The and D ports are tied together and connected to the rod end of the cylinder. The C port is plugged. t the beginning of the cycle the cylinder is fully retracted. To begin the cycle both handles are pulled back. Oil is directed to the port and the cylinder will extend until it reaches the end of its stroke. t this point the pressure will build to the detent release pressure and the first spool will center to neutral. Now the oil will go through the open center core to the second spool and is directed out the D port to retract the cylinder. When the cylinder reaches the full retract position the pressure will build to the detent release pressure and the second spool will center to neutral. This completes the cycle. To begin the next cycle both handles are again manually pulled back. Please note this valve does not have the loadcheck feature of the standard RD5200 valve. lso the port is open to tank in neutral. Maximum detent pressure setting is 2000 PSI. OUT YD D C Model Number RD525MMEE541 OUT YD D C CTV O.E.M. CUSTOMER SERVICE: (712) FX (605) DISTRIUTOR CUSTOMER SERVICE: PHONE (605) FX (712) OUT YD V59

60 RD5000 SERIES VLVE WITH PROPORTIONL OPERTORS RD5000 PROPORTIONL OPERTOR VLVE The RD5000 valve is available with proportional solenoid operators. The valve will allow controlled starts and stops of the work port flow as well as control of the work port flow rate over a limited metered range. Pilot pressure to initiate spool shift is provided internally by means of a pressure build-up cartridge in the power beyond port. Once the spool shift is initiated, load induced pressure is required to regulate the spool position and flow. y increasing the current through one of the solenoids, increasing pressure is applied to a spool end, causing the spool to shift against spring bias. Full spool shift is at approximately 1200 m - 12 VDC (600 m - 24 VDC). HCI-PRCE OUT YD The RD5000 proportional operators are typically controlled with a thumb or handle control and a PWM control module.

When both solenoids are de-energized both sides of the pilot piston are open to tank pressure and the spool remains spring centered. When solenoid is energized, pilot pressure is applied to one side of the pilot piston causing the spool to shift from the neutral position to work port. When solenoid is energized, pilot pressure is applied to the other side of the pilot piston causing the spool to shift to work port. In cases where the pilot pressure is provided by the inlet line or #4 SE port on valve, a Pressure uild-up Valve must be installed in the outlet port. Two versions of the pressure build-up valve are offered. The open center pressure build-up valve and the power beyond pressure build-up valve. oth versions supply PSI pilot pressure to the solenoid actuator. When remote pilot is used, the pressure build-up is not required. ecause the valve is internally piloted, overcenter or light loads can be a problem. The inlet pressure must be at least 200 psi during operation. Restrictors can be added to eliminate this problem. CTV O.E.M.

The LSR has been specifically designed to reduce system costs by allowing a single stage pump to be used in systems currently using two stage (hi-low) pumps. When extra splitting force is required, the LSR allows the user to manually shift from high speed mode to high force mode. soft stop differentiates between high force and high speed modes. Laboratory testing has not shown a significant difference in working cycle times between single stage/rapid extend systems and two stage systems. (Working cycle is the average time between extending the cylinder to split the first log and extending to split the next log after the split wood has been removed and a new log has been placed on the log splitter.)

The work port is plugged for this option. P-T This spool option is used to control a reversing motor or a double acting cylinder. In neutral the work ports are connected to tank and oil goes through the open center passage to the outlet. This allows a motor to free-wheel or a cylinder to float in the neutral position. P-T The load check feature is standard on all RD-2500 valve models. The load check will prevent the fall of a cylinder as the spool is shifted. It does this by preventing the back-flow of oil from work port to inlet. The pump must build up enough pressure to overcome the pressure on the work port and lift the load check poppet. The load check has nothing to do with holding a cylinder when the spool is in neutral. CTV O.E.M.

75 PRESSURE COMPENSTED DJUSTLE FLOW CONTROL MODEL RD-100 TOP PORT FLOW CONTROL MODEL RD-1900 SIDE PORT FLOW CONTROL The PRCE valve models RD-100 and RD-1900 are pressure compensated adjustable flow control valves. y rotating the handle, the flow out the CF, or controlled flow port, can be varied from approximately 0 to the maximum controlled flow shown in the chart below. ny remaining flow is bypassed to the EF or excess flow port. This flow can be used to power another circuit or can be returned to tank. Once the controlled flow is set it will remain nearly constant with variations in pressure on either the controlled or excess flow ports. Please note: If during operation the controlled flow port is blocked the valve will compensate in such a way as to shut off flow to the excess port. These valves can also be used as a restrictive flow control by plugging the excess flow port. The PRCE valve models RDRS-100 and RDRS-1900 have a built in adjustable pressure relief. For these models the excess flow port must be connected to tank. It should be noted that whenever these or any valve is used to bypass or restrict, flow heat will be generated. Steps may be required to keep oil temperature from becoming too high.

77 CONSTNT VOLUME PRIORITY DIVIDERS MODEL RD-400 FIXED FLOW PRIORITY DIVIDER The PRCE model RD-400 is a constant volume priority divider. It can be used in applications where two circuits are to be supplied by a single pump such as power steering systems. In operation the flow of oil supplied to the inlet is divided into two flows, the priority flow and the excess flow. The priority flow will remain nearly constant with variations in pressure on either the priority or excess flow port and will also remain nearly constant with variations in the inlet flow. The priority flow GPM is determined by a fixed orifice inside the main spool. The desired priority GPM must be specified with model number, see below. The PRCE model RD-400R provides the same function as described above with the addition of a built in pressure relief for the priority port only. This relief is internally adjustable and requires a separate line to tank. The relief is factory set at 1500 PSI.

85 MODEL DS DOULE SELECTOR VLVE The PRCE valve model DS is a manual 6-way 2 position double selector valve. This valve will divert the flow going to two separate hydraulic circuits. For example two double acting cylinders or two reversible hydraulic motors can be operated by one four-way valve. When the double selector spool is pushed in, the C and D ports (top ports) are connected to the and E ports (right ports). When the selector spool is pulled out, the C and D ports are connected to the and F ports (left ports). n optional series/parallel spool is also available. This spool will run two reversible hydraulic motors in series when the spool is out and in parallel when the spool is pushed in.

86 PILOT-OPERTED CHECK MODEL RD-1400 LOCK VLVE DOULE PILOT-OPERTED The PRCE valve model RD-1400 is a double pilot-operated lock valve. This valve will lock a cylinder in place when a directional control valve is in the neutral position. In operation oil is directed to one of the valve ports and oil can free flow to the corresponding cylinder port. The pressure on this valve port will shift the pilot spool opening the opposite check valve. This will allow oil to return through the opposite check valve. This valve has a hardened steel seat and steel ball and therefore should not be used in applications requiring absolutely zero leakage. When using a pilot operated check to lower a heavy load the valve may chatter. n orifice in the line in some cases may be beneficial CYLDER PORTS TO CYLDER TO CONTROL VLVE RD DI (3) STNDRD MODELS VILLE MODEL NUMER PORT SIZE RD /2 NPTF RD /4 NPTF VLVE PORTS 3.88 VLVE SPECIFICTIONS: Capacity: 30 gpm max inlet flow Pressure: 3000 psi max Weight: 7 lbs.
