P3W Pressure and Temperature Relief Valves
The P3W Pressure & Temperature relief Valves provide protection against both excess temperatures as well as over pressurisation. The valves will automatically discharge hot water at the predetermined set pressure and/or temperature. Each of the lift mechanisms will work independently of each other. The valve is designed to be used on hot water boiler applications.
The P3W Pressure & Temperature relief valves has WRAS approval.
