Express 3/4" Safety Relief Valve - No Guage

Express safety relief valves have been designed to protect closed circuit water heating systems from over pressure which can build up as a consequence of heating the water or any other fault conditions resulting in excessive pressure. Available with 3/4" connections and a range of pre-set discharge pressures. As the pressure inside a system rises to the level of the pre-set safety valve, the valve will automatically open and discharge the air to atmosphere, preventing the pressure inside the system rising to a level which could cause damage to system components and potential catastrophic damage to the boiler or hot water cylinder. Consideration should be given to select the appropriate pre-set pressure for the system.
