Safety valve from the company Farg, suitable for use in a boiler. The safety valve is installed in a central heating system to protect it from excessive operating pressure. When the pressure exceeds a predetermined value, it opens to decompress the system. Its role in the installation is very important because increased pressure poses serious risks to people and materials. It is installed at the highest point of the installation without the intervention of any switch or valve.

It is two-way, meaning it has 2 ports, one for the inlet of the medium and one for the outlet. When the inlet is closed, the flow is interrupted, while when it is open, the flow at the inlet is the same as the flow at the outlet.

It is made of brass, which is an alloy of copper and zinc, and it shows good resistance to corrosion while also being durable over time.
