The safety valve from Caleffi is an excellent choice for use on boilers. Designed to protect the central heating system from overpressure, it opens when the pressure exceeds a preset value, allowing the system to decompress. This process is essential for the safety of both people and materials, given the risks associated with increased pressure. The valve is installed at the highest point of the system and operates automatically, without the need for other switches or valves.

The special double-ported design of the valve includes two ports: one for the intake of the medium and one for the outlet. This means that when the inlet is closed, the flow is also interrupted, while when it is open, the flow at both the inlet and outlet remains the same.
