This is a direct-operated, spool-type, normally open electro-proportional flow control valve. When de-energized, the valve is opened with a spring-bias spool. When energized, the current proportionally closes the spool to control the metered flow from port 1 to port 2. When the pressure drop is higher, this valve performs self-compensation from port 1 to port 2. Direction in port 2 to port 1 is not pressure-compensated. If you need precise flow proportional control (port 1 to port 2 or port 2 to port1), we recommend using with Winner's full series of compensators.
