Düker GmbH

Ductile cast iron gate valves

Düker gate valves are used all over the world and are subject to very high requirements, especially when it comes to drinking water.


This is why all gate valves are developed and manufactured applying the greatest possible care and attention to detail. Needless to say, before any product leaves Dueker, it is thoroughly put to the test.

All Düker gate valves are made of ductile cast iron, which is a material with good properties to withstand internal and external pressure.


In addition the coating guarantees permanent corrosion protection as well as reliable hygiene in our drinking water supply system.


Therefore all Düker gate valves receive a seamless and pore-free epoxy powder coating or are completely enamelled.
