DN32 P3W Relief Valve P3W32A4177
- Product Code: P3W32A4177
The P3W Pressure & Temperature valve provides protection against both excess temperature as well as over pressurisation. The valve will automatically discharge hot water at a 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.
