The Altecnic / Caleffi 311 Safety Valve - 311460 is an essential component for domestic hot water systems, providing crucial protection for hot water cylinders and heating systems, including boilers and associated components. This valve is specifically chosen based on the required set pressure. When the pressure within the system exceeds the designated threshold, the valve activates, releasing excess pressure into the atmosphere. This mechanism effectively prevents potentially dangerous pressure levels that could harm the boiler, hot water storage cylinder, or anyone nearby.
