Designed for demanding hydraulic circuits requiring fast response and low hysteresis, this is a pilot-operated two-stage pressure relief valve.

It blocks the flow from Port 1 to Port 2 until the preset pressure is reached at Port 1. When the system pressure reaches the adjusted pressure setting, the pilot relief mechanism is activated, allowing the main stage to open and enabling flow from Port 1 to Port 2.

The desired pressure setting can be precisely adjusted via the socket head screw located on the valve.

Note: This valve is not suitable for cross-line relief applications.
