The two-way safety valve is designed for use in boilers, providing the necessary protection against excessive pressure in the central heating system. If the pressure exceeds a set value, the valve automatically opens, allowing the system to decompress and minimizing the risks arising from increased pressure.

The characteristic of being two-way means it has two ports: one for the inlet of the medium and one for the outlet. Thus, when the inlet is closed, the flow is interrupted, while when it is open, the inlet and outlet flows are equivalent. This valve is installed at the highest point of the installation and operates without the need for a switch or tap, ensuring safe and efficient operation of the heating system.
