The Caleffi safety valve is ideal for protecting your boiler room from excessive pressure. This two-way valve is designed for installation on boilers and functions to ensure the safety of the central heating system. When the pressure exceeds the set value, the valve automatically opens to relieve the system, thereby preventing serious risks to people and equipment. It is installed at the highest point of the setup, guaranteeing safe flow control without the need for switches or valves.

Its two-way construction means it has two ports: one for the inlet of the medium and one for the outlet. This allows for uninterrupted flow, as when the inlet is closed, the flow is stopped, while when it is open, it is the same as the outlet.
