SYMBOL
DESCRIPTION
Electromagnetic drive, variable electrical parameters, 2-way, pressure compensated, spool type, normally closed when off power, proportional flow control valve.
OPERATION
The E-PV72-20 will adjust the flow of oil port 2 without being affected by the working pressure of the system. As the current in the solenoid valve increases, the output flow of the E-PV72-20 increases.
Emergency manual operation: when starting: rotate clockwise for about 1 turn to reach the starting point. The maximum displacement can be reached by further rotation of about 5 turns. At the end: rotate counterclockwise for about 6 times until the positive direction appears.
FEATURES
* Hardened precision spool and cage for long life.
* Voltages of cartridge valves are interchangeable
* Cartridges are voltage-interchangeable.
* Manual Override option.
* Solenoid voltage and termination optional.
* Efficient wet-armature construction.
* Unitized, molded coil design.
* Coil waterproofing standard.
