The TS 131 safety temperature relief valve is designed for heating systems according to EN 12828. It is a direct-acting regulator controlled by the temperature of the outlet water from the heat source. At a medium temperature of 95°C, it opens and releases water from the heat exchanger or hot water storage tank, thus protecting it from exceeding the maximum temperature.

Materials: Valve body, spring cover, and temperature sensor well made of brass; double temperature sensor made of copper; capillary made of copper; valve cone made of brass; valve seat seal made of elastomer resistant to hot water.
