Operating principle:

The valve remains closed under normal operating conditions. ? The valve is calibrated to a specific pressure by adjusting the spring with the pressure nut.

When the pressure in the pipeline exceeds a specific pressure, the valve opens to allow fluid to pass through, thereby reducing the pressure in the pipeline system. The valve can be equipped with a handle to partially open the valve. When the handle remains open during on-site cleaning, the cleaning product can flow through the valve.
