Product Operation Symbol
The Proportional pressure flow compensation valve 23BL-70-30 will regulate flow out of port ③ regardless of system working pressure. With an increasing current applied to the solenoid, the Proportional pressure flow compensation valve 23BL-70-30 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.
Operation of Manual Override Option
To Engage Turn clockwise approximately 1 turn to reach the start point. Continue another approximately 5 turns to full shift.
To Disengage Turn counterclockwise approximately 6 turns to positive stop.
