Resideo EW110 Water Meters

The Reliance Water Controls (RWC) TPR22 Pressure & Temperature Relief Valves are expertly designed compact valves that ensure protection against over pressurisation in unvented hot water systems. These essential valves are mounted at the upper part of a hot water cylinder, where the hottest temperatures are found. Should the system exceed 95°C, the specially formulated wax mixture within the temperature probe expands, lifting the valve off its seat to release water, thereby alleviating pressure within the cylinder. Furthermore, in the event of increased water pressure (without a corresponding temperature rise), the valve remains closed until the designated pressure limit of the relief mechanism is reached. At that point, the valve opens to relieve excess pressure. Some variants are available with a PTFE coating on the MBSP inlet thread, facilitating quicker installation.
