SYMBOL
DESCRIPTION
A solenoid-operated, electrically-variable, 3-port, pressure-compensated, spool type, normally closed when de-energized, proportional flow control valve. It can be used as a priority-type flow regulator with pressure-compensated, regulated and bypass flow. It can also be used as a restrictive-type 2-way, pressure-compensated flow regulator when the bypass line (port 2) is blocked.
OPERATION
The E-PV08-30 will regulate flow out of port 3 regarless of system working pressure. With an increasing current applied to the solenoid, the E-PV08-30 will increase output flow.
Note: When used as a bypass flow control in applications where the priority flow port will be blocked by external valving (dead-headed), a small bleed orifice is required at the priority port (port 3). Consult factory.
FEATURES
* Excellent linearity and hysteresis characteristics.
* Hardened spool and cage for long life.
* Optional coil voltages and terminations.
* Efficient wet-armature construction.
