HydraForce Flow Control PV70-30 Spool-Type Valve, 3-Port, Normally Closed


HydraForce PV70-30 solenoid-operated, three-port, pressure-compensated, spool-type, normally closed when de-energized, proportional flow control regulator.

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.

With inlet flow at port 1, the PV70-30 will regulate flow out of port 3 regardless of system working pressure. With an increasing current applied to the solenoid, output flow will increase.

Flow range: PV70-30A | PV70-30B
