The Caleffi safety valve is ideal for use on boilers and is recommended for every central heating system. Its primary function is to protect the system from excessive operating pressure. When the pressure exceeds a set value, the valve opens and relieves the system, thereby preventing serious risks to people and materials. It is installed at the highest point of the installation without the need for any switch or vent adjustments.

It is a two-way valve, which means it has two ports: one for the inlet of the medium and one for the outlet. This ensures that when the inlet is closed, the flow is interrupted, while when it is open, the inlet and outlet flow remains the same.
