Tempering valves blend hot and cold water to deliver mixed water at a constant temperature. They incorporate a temperature sensitive element which expands and contracts depending on the temperature of the water flowing across it. This action of the element in turn moves a piston which shuttles between the hot and cold ports. In doing so the valve maintains an essentially constant outlet temperature, and thus reduces the risk of scalding accidents. Reliance is a world expert in this field.
RMC has developed a comprehensive range of tempering valves to suit all types of water heater installations.
