The safety valve from Renner is ideal for use in boilers, ensuring the protection of the central heating system from excessive pressure. If the pressure exceeds the pre-set limit, the valve automatically opens, allowing the system to depressurize and preventing dangerous situations. Its installation is critical for safety, as the valve is positioned at the highest point of the installation without the need for a switch or valve.

Its double design includes two ports: one for the inlet of the medium and one for the outlet. When the inlet port is closed, the flow stops, while when it is open, the flow is equal on both the inlet and the outlet.
