DUCO safety valves for DHW, heating and drinking water

DUCO safety valves are designed for hot water closed heating systems and hot water heaters, even for drinking water. Their main advantage is the presence of an additional safety cap. This prevents tampering by unauthorised persons and therefore possible damage. The DUCO safety valve has a seat made of silicone rubber, which is absolutely wear-free and also prevents the risk of sticking to the seat even at high temperatures. For the production of the separation membrane we use the proven EPDM rubber, characterized by low flammability and stable resistance to adverse influences.

DUCO safety valves are also for drinking water (safety valve with blue cap). These valves are marked as TUV (TV).

A common problem is that the safety valve to the boiler drips. In this case, the pressure in the heating system must be checked and the safety valve replaced if necessary.
