If you manufacture, distribute, or use valves for potable water or food processing. You will most likely have come across the acronym NSF who confirms and certifies. Also, a valve that does not clearly have a NSF Certifications ratings should not be used for distributing. In addition, Especially potable water or in food processing.
Passing NSF Certifications?
Above all, using a valve that isn’t certified when you have an application that calls for a NSF Certifications. This is not a good approach and will not pass state and federal inspections, and is simply against the law.
What is NSF Certifications?
NSF stands for the National Sanitation Foundation. When a valve, fitting, or pipe is NSF certified, it meets or exceeds particular standards. These Standards are enforced by state and federal laws. Not all NSF standards pertain to food or water.
NSF Certification Standards?
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 certifications. Furthermore, if the applications requires one, you should contact a valve expert before installation.
Safety and Protection
It’s all about safety and protecting yourself from possible liability and suit. An inspection that fails to identify NSF certified valves in place, where they should be could be very costly. In addition, this can be very devastating to a business or municipality depending on how many valves. Also, It will depend on other line components would have to be immediately replaced.
Identifying NSF Certifications
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. Furthermore, some will list valves as being certified. While others will let you know which valves are not certified.
In conclusion, if NSF certifications isn’t mentioned on the manufacturer data sheet, it’s best to contact them directly.
Also, 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.
