The safety valve from Caleffi is ideal for use in boilers, providing guaranteed protection against excessive pressure. When the pressure in the central heating system exceeds preset values, this valve automatically opens, allowing the system to depressurize and preventing dangerous situations. It is essential to install it at the highest point of the installation, ensuring proper operation without the need for a switch or drain valve.
The Caleffi 258603 is a two-way valve, meaning it has two ports – one for the medium's inlet and one for the outlet. When the flow is closed at the inlet, the flow is stopped, and when it is open, the flow to the outlet equals that at the inlet.
