  • Technical Feature

    OPERATION:

    Pilot-operated, 2-way, directional cartridges valve, normally closed, the valve shifts when the pressure differential between port and port exceeds the setting. Pressure at port is directly additive to the setting of the valve. Because of this, port ③ may not be useable as a work port in your circuit. Port can be blocked to prevent the valve from shifting and Maximum pressure at port should be limited to 3000 psi (210 bar).
