The safety valve from the company Watts is suitable for use in boilers. Designed to protect central heating systems from excessive operating pressure, it automatically opens when the pressure exceeds the preset value, allowing the system to decompress. Its mechanism is vital for safety, as increased pressure can cause serious risks to people and property.

It is installed at the highest point of the installation, without the need for an intermediary switch or valve. The valve is two-way, meaning it has two ports: one for fluid intake and one for discharge. When the intake is closed, flow is interrupted, while when it is open, the intake flow equals the discharge flow.
