Pressure overflow valve、One-way pressure overflow valve

Explanation: When the partial pressure of the circuit is set below the pressure of the main circuit, it should be used. In addition, remote control loop can be used for remote control. With one-way valve type, liquid flow can be allowed to flow freely from the secondary side to the primary side.

Maximum flow rate is the value of 21 MPa primary pressure.

Controlled Flow Rate of Oil Leakage Equivalent to Primary Pressure and Secondary Pressure Difference of 20.5 MPa

Base plate

When using the bottom plate, please order according to the model of the bottom plate of the left table. When the bottom plate is not used, the installation surface must be machined with 6-S precision. The bottom plate is shared with H-type pressure control valve. But for pressure relief valves, the bottom plate is turned 180 (upside down) from the conventional position for use. And the valve positioning pin must be loaded into the bottom pinhole. Dimensions refer to floor dimensions.

Attachment

Use precautions

When adjusting the pressure, first loosen the locking nut, then turn the handle clockwise when boosting and counterclockwise when lowering the pressure. After adjusting the pressure, the locking nut must be tightened.

Because the back pressure of the outlet is near the atmospheric pressure, the piping of the outlet should be directly connected to the tank.
