The WR60 / WR80 adjustable pressure relief valve or pressure safety valve allows users to set the desired relief cracking pressure right at the valve by simply turning the adjustment screw. Installing a pressure-relief valve can protect pumps in a process line by allowing the pump to discharge pressure if it exceeds the cracking pressure set on the valve.
The Waukesha WR60 adjustable pressure relief valve provide external protection to your sanitary positive displacement pump. If the pump discharge pressure exceeds the set cracking pressure, the valve will open to a relief path.
The adjustable-spring actuator allows users to set the desired relief cracking pressure at the valve simply by turning the adjustment screw. And because the valve is air actuated, it can be bypassed completely during CIP without having to over-pressurize the valve or flow path.
