A Multiplex 00701336 Pressure Relief Valve releases excess pressure to protect internal components and maintain stable system function.
The pressure relief valve regulates system pressure by opening at its rated threshold to release excess pressure and protect connected components from strain or damage. Its 130LB rating and 1/4" Outside NPT connection are important because they provide the correct pressure response and secure fit needed for safe, consistent operation.
The pressure relief valve may be failing if the system experiences unstable pressure, frequent venting, reduced performance or difficulty maintaining normal operating conditions. Physical signs can include leaks, corrosion, mineral buildup or visible wear around the valve and environmental signs may include unusual moisture, escaping fluid or pressure discharge in the surrounding area.
