The Altecnic / Caleffi 311 Safety Valve - 311560 is specifically designed for use in domestic hot water systems, providing essential protection for hot water cylinders, as well as in heating systems to safeguard boilers and other components. This valve is chosen based on the required set pressure. When system pressure increases and reaches the discharge threshold, the valve opens, releasing excess pressure to the atmosphere. This crucial function prevents the pressure from escalating to dangerous levels within the system, ensuring the safety of the boiler, hot water storage cylinder, and any personnel nearby.
