Reliance RWC TPR22 Pressure & Temperature Relief Valve 3/4" x 22mm 10 Bar - PTEM575210

The Reliance Water Controls (RWC) TPR22 Pressure and Temperature Relief Valves are compact devices specifically engineered to safeguard unvented hot water systems against the risks of over-pressurisation. This risk arises when the input temperature or pressure controls fail. The valves are designed to be installed at the upper section of a hot water cylinder, where the highest temperatures are present. If the system temperature exceeds 95°C, the wax mixture within the temperature probe expands, lifting the valve off its seat to release water, thereby alleviating the pressure within the cylinder. Furthermore, should the water pressure rise (without a corresponding temperature increase), the valve remains closed until the preset pressure limit is achieved, at which point it opens to relieve the excess pressure. Certain models are equipped with a PTFE coating on the MBSP inlet thread, streamlining the installation process significantly.
