SYMBOL
DESCRIPTION
A solenoid-operated, electrically-variable, three-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-PV72-30 will regulate flow out of port 3 regardless of system workign pressure. With an increasing current applied to the solenoid, the E-PV72-30 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, bypass pressure drop will increase unless a small amount of leakage is provided for the priority port. Consult factory.
Operation of Manual Override: To Engage: Turn clockwise approximately 1 turn to reach start point. Continue another approximately 5 turns to full shift. To Disengage: Turn counterclockwise approximately 6 turns to positive stop.
FEATURES
* Excellent linearity and hysteresis characteristics.
* Optional coil voltages and terminations.
* Efficient wet-armature construction.
* Cartridges are voltage-interchangeable.
* Unitized, molded coil design.
* Coil waterproofing standard.
* Manual Override option.
