Surface protection


Corrosion protection for long-life fittings and clean water is the focus of the butterfly valves from ERHARD.
You have the choice between two standard coatings:

- EKB epoxy plastic coating

- ERHARD Pro email

The epoxy coating is the classic coating solution and has proven itself in connection with most of the common requirements. EKB is physiologically harmless and has been tested and certified by the DVGW Research Center TZW Karlsruhe, the Hygiene Institute Gelsenkirchen and the WRAS (WRc) in Great Britain. Pro email coating is a glassy, high-strength material, which forms a permanent connection with the cast iron. Because of that is has a extremly smooth surface for hygianically perfect conditions and it's environmental compatibility.

If required, we also offer customer-specific solutions that are tailored to the respective application.
