Düker GmbH

Ductile cast iron valves

The most important attributes of ductile cast iron pipeline systems are reliability and economic efficiency, as a result of permanent corrosion resistance.

Effective and long-lasting surface protection means being able to withstand any given situation and, as a result, assures protection against corrosion.


Therefore all our valves (standard version) are enamelled inside and outside special Düker etec enamel according to the DEV guidelines and EN ISO 11177. Alternatively a completepowder epoxy coating according to the rules of GSK is available.
