1 Proportional solenoid flow control valves EPF(R)G his valve is a flow control valve which utilizes a proportional solenoid actuator. proprietary flow adjustment design is incorporated to allow very precise positioning of the main spool. his flow control valve is pilot operated, and the main spool is impervious to effects of flow forces and other disturbances. he EPFRG valve utilizes a bypass type pressure compensator with load sensing function which contributes to energy saving of hydraulic circuits. Functional Symbols EPFG-** EPFG-**-F - EPFRG-**-S EPFRG-**-F-S V V P P Note: EPFRG-/ has no V ports (vent).

However if valve is mounted on the lateral side of the manifold block, and none of the air bleed plugs do not face the ceiling, rotate the proportional solenoid 9 to orient an air bleed plug to the ceiling. Current-flow characteristics may vary slightly (approx..%) according to the mounting direction. ir bleed For stable flow control, loosen the air bleed plug and bleed air completely out of the valve prior to use. Manual operation In case there is no input current to the solenoid during initial adjustment or electric malfunction, press the manual pin for flow control such as Inching.

Readjustment is not necessary. Drain piping allowable back pressure is. MPa. Piping should be directly returned to tank. Ensure that end of the piping is always below the fluid level. Valve and actuator piping Care should be paid when the vent line piping is long as the large volume of fluid in the pipes may cause instability (resonation). Piping should be as short as possible. For optimum flow control, differential pressure should be more than or equal to the values shown in the below table. 大きさの呼び Size Valve Differential 弁差圧 Pressure MPa MPa.
