PARALLEL CIRCUIT SVW, SVM, SVF, SVH, SVR, SVG AND WORK SECTIONS Parallel circuit sections are by far the most common. The SVW, SVM, SVF, SVH, SVR, SVG and 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. ENHANCED 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.28 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 0 gpm or less. For enhanced metering on higher flows, it is recommended that the SVM or SVR be used. LOCK SECTIONS The 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 PASSAGE LOAD CHECK PARALLEL CIRCUIT CORE CONVERSION PLUG A 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. TANK RETURN TANK RETURN (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 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. COMBED SERIES / PARALLEL 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. Both 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 TANK RETURN TANK RETURN TANK RETURN TANK RETURN of any downstream valve sections and that a work port relief in the section will also limit the pressure of any other sections in the valve. The series motor spool should not be used to control a hydraulic cylinder as unwanted cylinder drift may occur in the neutral position. CLOSED CENTER APPLICATIONS The SV Series Circuit Valve sections cannot be used in a closed center valve assembly.

SIDE LET SV OUTLET COVER OPTIONS POWER BEYOND PORT POWER BEYOND PORT SVEXX SIDE OUTLET "CC" STAMPED ON END OF SIDE OUTLET CLOSED CENTER PLUG OPTION 3 CLOSED CENTER OUTLET This option provides for closed center operation. This is typically used with a variable displacement pressure compensated pump or in a system with an unloading valve. When the spools are in neutral the inlet port is blocked. Closed center can also be accomplished by plugging the power beyond port of option 2..00.00 OPTION SVEXX STANDARD OPEN CEN- TER OUTLET WITH CONVERSION PLUG This is the standard outlet option. This option allows for conversion in the field for power beyond or closed center applications. When spools are in neutral the inlet is unloaded to tank. OPTION 2 POWER BEYOND OUTLET WITH #8 SAE BEYOND PORT This option provides for a high pressure power beyond port. This would be used if a valve is to be added down stream. THE OUTLET PORT MUST STILL BE CONNECTED TO TANK. When spools are in neutral the inlet is connected to the power beyond port.

Port Size #8 SAE ORB (3/4- THD) DESCRIPTION: A Mid-Inlet provides an inlet port for a second pump mid stream in the valve stack. A relief can be provided in this section. With the combined flow the flow from both pumps is available to the downstream sections when all the work sections upstream are in neutral. The split flow completely separates the two pump flows. The common tank passage is all that is shared between the two pump flows. Note: Split flow mid inlet is not available when used after a series section and the core block plate is not used after a series section. CATV 37---0 O.E.M.

FLOW CONTROL OPTIONS: P OPTION incorporates a solenoid operated, electrically variable pressurecompensated flow control cartridge. With the solenoid de-energized, all of the inlet flow is diverted to the tank core/ef port. By increasing the current through the solenoid, the flow directed to the power core and downstream sections will be proportionally increased, (the maximum rating of the cartridge is gpm at 500 ma) Control current is normally provided via a controller card providing, a PWM signal. U OPTION incorporates a solenoid operated, unloader cartridge. With the solenoid de-energized, all of the inlet flow is diverted to the tank core/ef port. With the solenoid energized all the inlet flow is directed to the power core and downstream sections. M OPTION incorporates a manually Option P- Proportional flow control with manual operated override pressure-compensated flow Option P- Proportional flow control cartridge. With the control knob control with manual 5.8 override turned fully in (clockwise), all of the inlet flow is diverted to the tank core/ EF port. By turning the flow control knob counter clockwise, the inlet flow directed to the power core and downstream sections is proportionally increased. Approximately 5 revolutions varies flow from no flow to full flow, C-70 PORT OPTION 2 The flow being directed to the tank core/ef port may be utilized by a second circuit by inserting a /4 pipe plug into the tank core passage on the seal side of the casting and then connecting the EF port to the second circuit.
