Ferro's safety valve is ideal for use in boilers, providing protection for central heating systems from excessive operating pressure. When the pressure exceeds a preset value, the valve automatically opens, allowing the system to decompress. Its role is crucial, as increased pressure can pose serious safety risks and threaten the integrity of the materials. It is easily installed at the highest point of the installation, without the need for additional switches or shutdown systems.

The Diodi valve features two ports: one for the inlet of the medium and one for the outlet. When the inlet port is closed, flow is interrupted, but once it opens, the flow at the outlet equals that at the inlet, ensuring the system operates steadily.
