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-PV76-30A will regulate flow out of port 3 regardless of system working pressure. With an increasing current applied to the solenoid, output flow will increase. 
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.
