Contact usPV76-31A Proportional Flow Control Cartridge, (PV76-31A)
A solenoid-operated, electrically-variable, three-port, pressure-compensated, spool-type, normally open 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, two-way, pressure-compensated flow regulator when the bypass line (port ➁) is blocked.
Product Operation
The PV76-31A will regulate flow out of port ➂ regardless of system working pressure. With an increasing current applied to the solenoid, output flow will decrease.
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.
