3 4/3 Proportional Directional Valve, Size SAE 0 Q max = 8.0 gpm [30 l/min], p max = 4000 psi [80 bar] Direct acting, sliding-spool design, with solenoid operation Series PDFC-0 Description Series PDFC 0 proportional directional valves are direct acting screw in cartridges with a sliding spool design and a 7/8 4 UNF mounting thread. In the neutral position, port 3 is closed and depending on the spool type, ports and 4 are connected to tank () (spool configuration M) or ports, and 4 are all blocked (spool configuration L). The version with the M spool is used in motor control circuits where free wheeling in the neutral position is required. The L configuration is the version to use for cylinder applications. These cartridges are particularly suitable for precise and controlled lifting and lowering movements and can also be used for reliable operation in mobile and industrial applications. Best controllability is achieved when using the valve with a bypass pressure compensator to control pressure drop through the valve. Using the valve without pressure Compact construction for cavity type C040 7/8-4 UNF Operated by a proportional high pressure wet-armature solenoid Minimum current threshold/ dead band (position b) is factory set for better consistency Manual over-ride optionally available, detented in neutral position Excellent reproducibility and repeatability, and low hysteresis All external parts zinc plated, passivated (CrVI-free) The slip-on coil can be rotated, and it can be replaced without opening the hydraulic envelope Various plug-connector systems and voltages are available Can be fitted in a line-mounting body compensator is not recommended because higher pressure drops cause the flow to be more restricted (see performance graph). The proportional directional valves is optionally equipped with a manual over ride which is detented in the neutral position. To unlatch the detent mechanism, the button on the back can be pushed. That allows shifting the valve in both directions. Pushing the knob shifts the valve to position (a) (3 and 4 ) and pulling shifts it to position (b) (3 4 and ). All external parts of the cartridge are zinc plated and chromited (CrVI-free). The slip-on coils can be replaced without opening the hydraulic envelope and can be positioned at any angle through 360. If you intend to manufacture your own cavities or are designing a line-mounting installation, please refer to the section Related data sheets.

9 EPRR-0 DESCRIPTION This unit is a electro-hydraulic, proportional, screw in cartridge style, direct acting, spool type, pressure reducing/relieving flow pressure control valve. OPERATIONS ELECTRO-HYDRAULIC, PROPORTIONAL, PRESSURE REDUCING/RELIEVING VALVE. When the coil is de-energized, this valve allows no flow or pressure from port to and port is open to (tank) port 3. When the coil is energized, the spool in this valve shifts and allows flow and pressure between ports and and blocks port 3 (tank). When the coil is energized the armature moves a precision bias spring against the metering spool thus varying the pressure at port (Reg.) proportional to the curent input. When the current is increased to the coil the pressure will increase and when decreased it will decrease. IN THE EVENT OF POWER FAILURE THE VALVE WILL REDUCE REGULATED PRESSURE AT PORT TO ZERO. FEATURES AND BENEFITS Continuous-duty, very low heat rise & waterproof solenoid coil. Interchangeable solenoid coils & terminations options available. Hardened precision fitted spool & sleeve provides reliable, long life. Very efficient wet - armature solenoid core tube construction. All external carbon steel parts are plated for longer life against the elements. All cartridge valves are 00% functionally tested. Industry common cavity. Reference: 50-P-00-EN-00/09.05

11 Prop. Pressure-Reducing / Relieving Cartridge, Size SAE 08 Q max = 7.0 gpm [6 l/min], p max = 3400 psi [40 bar] Seated pilot, spool-type main stage Series EPRT-08 Description Series EPRT-08 proportional pressure-reducing / relieving valves are size SAE 08 / NG 5, high performance screw-in cartridges with a 3/4-6 UNF mounting thread. Using the leak-free seat-type pilot cartridge, the secondary pressure in port is dependent on the electrical control signal and it can be continuously varied and set at any desired level. In control mode, the connection opens until the pressure in port reaches the preset level. If the pressure rises above the preset level, the control spool opens the 3 connection until balance is attained. These pressurereducing / relieving cartridges function as full-flow pressure relief valves from port 3 as soon as the reduced pressure rises above the valve pressure setting. A high degree Compact construction for cavity types: C0830 and AM - 3/4-6 UNF Operated by a proportional solenoid 3 pressure ranges available Full-flow secondary pressure relief Internal pilot-oil drain Pilot stage protected from dirt by gap filter Excellent stability over the whole pressure and flow range All exposed parts with zinc-nickel plating High pressure wet-armature solenoids The slip-on coil can be rotated, and it can be replaced without opening the hydraulic envelope Various plug-connector systems and voltages are available Can be fitted in a line-mounting body of functional stability is reached even if the back pressure in the tank line fluctuates. Three pressure ranges are available in order to obtain precise pressure settings over the whole pressure range. These pressure-reducing / relieving cartridges are predominantly used in mobile and industrial applications for reducing a system pressure. All external parts of the cartridge are zinc-nickel plated to DIN and are thus suitable for use in the harshest operating environments. The slip-on coils can be replaced without opening the hydraulic envelope and can be positioned at any angle through 360.

OPERATIONS ELECTRO-HYDRAULIC, PROPORTIONAL, PRESSURE REDUCING/RELIEVING VALVE. When the coil is de-energized, this valve will allow flow from port to port until pressure in port exceeds the spring bias then the spool will shift and block flow from port to port relieving pressure to port 3. When the coil is energized, the armature moves a precision bias spring against the pilot orifice thus varying the pressure at port (reg.) proportional to the current input regardless of the pressure at port. Excess pressure at port is relieved to port 3. When the coil current is increased the pressure will increase and when decreased it will decrease. IN THE EVENT OF POWER FAILURE THE VALVE WILL REDUCE REGULATED PRESSURE AT PORT TO 50 PSI. FEATURES AND BENEFITS Continuous-duty, very low heat rise & waterproof solenoid coil. Pressure in tank port (3) will add to the bias spring setting, and is limited to 000 PSI. Interchangeable solenoid coils & terminations options available. Hardened precision fitted spool & sleeve provides reliable, long life. A unique self aligning (floating) cage provides very low hysteresis and reliable operation. Very efficient wet - armature solenoid core tube construction. All external carbon steel parts are plated for longer life against the elements. All cartridge valves are 00% functionally tested.

39 EPFC-6 PROPORTIONAL, IN-LINE TYPE, FLOW CONTROL VALVE. DESCRIPTION This valve is a cartridge style, electro-hydraulic, proportional, in-line (RESTRICTIVE) type, pressure compensated, hydraulic flow control. Regulated flow 0.0 GPM [76,0 L/M] max. is proportional to the current input regardless of load or system pressure. OPERATIONS This unit is a direct acting (NO PILOT FLOW), electro hydraulic, pro- portional, pressure compensated, flow control valve. When the coil is energized the armature moves the metering orifice open against a pre- cision bias spring varying the flow. A pressure compensator spool (HYDROSTAT) modulates the flow at 00 PSI/6,9 Bar delta "P" providing the valve with a constant regulated flow regardless of load or system pressure. When current is increased to the coil the flow will increase, as the current is decreased the flow will decrease proportionally. IN THE EVENT OF POWER FAILURE THE VALVE WILL CLOSE. FEATURES AND BENEFITS Continuous-duty, very low heat rise & waterproof solenoid coil. Interchangeable solenoid coils & terminations options available. Hardened precision fitted spool & sleeve provides reliable, long life. Very efficient wet - armature solenoid core tube construction. All external carbon steel parts are plated for longer life against the elements. All cartridge valves are 00% functionally tested. Industry common cavity. Reference: 50-P-040-EN-00/09.05

59 Proportional 3/ Throttle Cartridge, Size 5 Q max = 30 l/min, p max = 50 bar Sliding-spool design, direct acting Series MDR3GN -5 Description Series MDR3GN direct acting proportional 3/ throttle valves are size 5, high performance screw-in cartridges with a 3/4-6 UNF mounting thread. They are designed on the proven sliding-spool principle. The straightforward design delivers an outstanding price/performance ratio. In the initial position (de-energised), port is closed and ports 3 are connected with the full flow rating. In control mode, the flow through the connection is varied in proportionally to the control current. Three types are available: Type A - standard model, for general use with or without compensator. Type Z - special model, only approved for use with compensator (max. p 5 bar). Type S600 - special model with optimised characteristic - Q = f (I), also only De-energised closed Compact construction for cavity type AM 3/4-6 UNF Very good reproducibility Reliable operation over the whole pressure and flow range (even with high pressure differentials) With optional manual flow setting All exposed parts with zinc-nickel plating High pressure wet-armature solenoids The slip-on coil can be rotated, and it can be replaced without opening the hydraulic envelope Various plug-connector systems and voltages are available Can be fitted in a line-mounting body suitable for use with compensator. With this model, the connection 3 is only used for unloading (see Performance Graphs). These cartridges are particularly suitable for precise and controlled lifting and lowering movements, but they can also be used for reliable operation in mobile and industrial applications featuring large pressure differences. All external parts of the cartridge are zinc-nickel plated to DIN and are thus suitable for use in the harshest operating environments. The slip-on coils can be replaced without opening the hydraulic envelope and can be positioned at any angle through 360. If you intend to manufacture your own cavities or are designing a line-mounting installation, please refer to the section Related data sheets.
