Caleffi 311 Series 6 Bar Pressure Relief Valve - 311460

The series 311 safety relief valves are used in domestic hot water systems to protect the hot water cylinder and in heating systems to protect the boiler and other components. The valve is selected for the required set pressure. As the pressure rises, when the discharge pressure is reached the valve opens and discharges to the atmosphere, preventing the pressure within the system from reaching levels that would be dangerous for the boiler, hot water storage cylinder and any personnel in the adjacent vicinity.
