The Unimac Safety Diaphragm Valve is ideal for use on boilers, protecting the central heating system from excessive pressure. This valve is designed to open when the pressure exceeds a preset value, allowing the system to depressurize, which is vital for the safety and proper operation of the boiler. It is installed at the highest point of the system, without the need for a switch or drain valve, ensuring immediate response in case of overpressure risk.

The diaphragm design of the valve includes two ports, one for the inlet of the medium and one for the outlet. This means that when the inlet is closed, the flow is interrupted, while the flow at the outlet corresponds to the flow at the inlet once it is open. This function ensures stable and safe operation of the system.
