Key for threaded, socket weld, grooved end ball valves.
De-alloying corrosion, known as ”dezincification,“ was effectively eradicated from valve products in the 1950s.
Today, however, this problem has returned with the increased use of high-zinc alloys (commonly referred to as
‘yellow brass’) in forged and cast valves typically produced outside the United States.
Dezincification selectively removes zinc from the alloy, leaving behind a porous, copper-rich structure that has little mechanical strength. The
physical 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 components in the waterway must not contain more than 15% zinc
in their chemical makeup. As a standard, NIBCO
®
bronze ball valves are made to be “dezincification resistant,”
which is a seal of quality and longevity.

Chemical Compatibility
Please consult the most current edition of the NIBCO Chem-Guide for recommendations regarding chemical compatibility of material exposure to specific media and media-treatment
additives. The NIBCO Chem-Guide is a general guide on the topic of chemical compatibility and is by no means an exhaustive resource on the subject. Ultimately, proper material
selection is the responsibility of the installer and/or end-user, taking into account all aspects of a system’s design and intended use.
