The Caleffi safety valve is ideal for use in boilers and ensures the safety of the central heating system. When the operating pressure exceeds the set value, the valve automatically opens, allowing the system to depressurize and protecting against serious hazards. Its installation at the highest point of the setup is critical, as it functions without the need for additional switches or valves. It is a two-way valve, featuring two ports: one for the inlet of the medium and one for the outlet. Additionally, when the inlet is closed, flow is interrupted, and when it is open, flow is equal in both ports.
