The Altecnic / Caleffi 311 Safety Valve - 311530 is an essential component in domestic hot water systems, designed to safeguard the hot water cylinder and heating systems by protecting boilers and other vital components. This safety valve is meticulously chosen according to the required set pressure. As system pressure increases, the valve automatically opens at the discharge pressure to release excess pressure safely into the atmosphere, thereby preventing dangerous pressure levels that could jeopardise the boiler, hot water storage cylinder, and the safety of personnel in proximity.
