What is NSF Certification? valterra valve

If you manufacture, distribute, or use
valves for
potable water or food processing, you most likely have come across the acronym NSF.  A valve that does not clearly have a NSF rating should not be used for distributing potable water or in food processing.  Using a
valve that isn’t certified when you have an application that calls for a NSF Certification will not pass state and federal inspections, and is simply against the law.

What is NSF?

NSF stands for the
National Sanitation Foundation.  When a valve, fitting, or pipe is NSF certified,
it meets or exceeds particular standards enforced by state and federal laws.  Not
all NSF standards pertain to food or water.  There are numerous standards for a variety of medias.  Many relate to commercial and residential plumbing.  Others are
for pharmaceutical safety, etc.  The point is, if the valve you want to purchase and
use in your application does not carry an
NSF certification and the applications requires one, you should contact a valve expert before installation.  It’s all about safety and protecting yourself from possible liability and suit.  An inspection that fails to identify NSF certified valves in
places where they should be could be
very costly, even devastating to a business or municipality, depending on how
many valves and other line components would have to be immediately replaced.

Identifying NSF Certification

Most manufactures will have the NSF seal of approval on their submittal sheets or specification sheets to inform you upfront as to whether
or not a valve is NSF certified.  Some will list valves as being certified, while
others will let you know which valves are not certified.  If an
NSF certification
isn’t mentioned on the manufacturer data sheet, it’s best to contact them directly.  In addition, since there are so many different reasons for a product to be NSF
certified, the acronym NSF may be followed by a series of numbers specifying its specific media certification.  For instance, a marking of
NSF-61, or NSF/ANSI 61, indicates the valve
or other related product has been approved for a potable water application.
