EnglishDuctile 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 survace protection means being able to withstand any given situation and, as a result, assures protection against corrosion.
Therefore all our valves are inside and outside coated with special Düker enamel according to the rules of DEV. Alternatively a complete epoxy-coating according to the rules of GSK is available.
