A cartridge-style 2-way pilotoperated spool-type internal-vent directional valve

Technical Feature

OPERATION:
Pilot-operated, 2-way, directional cartridges valve, normally closed, the valve shifts when the pressure differential between port ① and port ③ exceeds the setting. Pressure at port ③ 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 ③ can be blocked to prevent the valve from shifting and Maximum pressure at port ③ should be limited to 3000 psi (210 bar).
