Even in the unlikely event that double pressure occurs, installing this valve on the pull-side connection port will release hydraulic oil from the safety valve to prevent damage to the cylinder, coupler, high-pressure hose, etc.● The maximum working pressure of this valve is 70 MPa, and this valve will be activated at about 80 MPa. ● Discharges from port A or B only while the “PUSH” or "PULL" button on the remote controlled operating switch is pressed and stops automatically at the pressure set by the pressure switch. Even when the SW-4WP button is released, the check valve maintains pressure for a long time.● An emergency oil vented port is connected between the pilot operated check valve and the discharge port for easy pressure relief.
