Hydrastore Proportional Priority Flow Control

A manifold control system comprising of separate proportional metering control and 3 port bypass compensator. The proportional valve is normally closed in the de-energised condition. In this state there is zero priority flow – all oil supplied is passed to bypass. As current supplied to the proportional valve increases a priority flow is supplied, excess flow is then bypassed. In the event of any load variation a constant flow output is maintained. The bypass line can be pressurised but bypass pressure must be lower than priority pressure to maintain compensation on the priority line. These valves are used in a wide variety of applications where remote variable supply to actuators is required.
