A solenoid-operated, electrically-variable, three-port, pressure-compensated, spool-type, normally closed when de-energized, proportional flow controlvalve. lt 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.

The IPV70-30 will regulate flow out of port ③ regardless of system working pressure. With an increasing current applied to the solenoid, the IPV70-30 will increase output flow.
When used as a bypass flow control in applications where the priority flow port will be blocked by external valving, the bypass pressure drop will increase unless a small amount of leakage is provided for the priority port. Consult Inno.
Turn clockwise approximately 1 turn to reach the start point. Continue another approximately 5 turns to full shift.
Turn counterclockwise approximately 6 turns to positive stop.
