Thephysical attributes of an in-service valve with Dezincification includes a white powdery substance or mineral stains on its exterior surface.What’s the cure? On all bronze valves the metal <strong>com</strong>ponents in the waterway must not contain more than 15% zinc in their chemical makeup.As a standard NIBCO bronze pressure-rated valves are made to be “Dezincification Resistant,” which is a seal of quality and longevity.This key is a guide only and is not intended to infer that any valve will be produced that is contained in the key.*Viton and Teflon are registered trademarks of DuPont.4NIBCO INC.
