NSF Certifications

NSF Certifications

NSF International, formerly known as the National Sanitation Foundation, is an independent non-profit organization that provides standards development, product certification, auditing, education, and risk management for public health and safety. Additionally, here are some details related to NSF certifications:

Purpose of NSF Certification

The main aim of NSF certification is to protect food, water, consumer products, and the environment. Additionally, the NSF mark on a product means that the product (Tri-Clamp, Sanitary Actuators, Ball Valves, Pressure, Level, Temperature) complies with all standard requirements.

NSF/ANSI Standards

NSF has developed over 80 public health and safety American National Standards (ANSI). For example, NSF/ANSI 61 is for drinking water system components, and NSF/ANSI 42 is for residential drinking water filtration devices.

Certification Process

The process typically involves product testing, materials analysis, facility inspections/audits, and market surveillance. Also, this process is designed to confirm that a product meets the specifications of applicable standards.

Product Categories

NSF provides certification for a wide range of products like food equipment, dietary supplements, drinking water treatment and distribution systems, pool and spa equipment, plastics, and pesticides.

Global Recognition

NSF International is widely recognized for its credibility and authority in certification. It’s accepted by authorities around the globe.

Continued Compliance

Once a product is certified, NSF performs periodic facility audits and product testing to ensure the product continues to comply with the standard.


All products that meet NSF standards are included in an online listing database that can be accessed by anyone. Remember, not all products require NSF certification. In addition, it’s typically used in industries where product quality and safety are a major concern, such as food, water, and health sciences.

If you manufacture, distribute, or use valves for potable water or food processing.  You will most likely have come across the acronym NSF which confirms and certifies.  Also, a valve that does not have NSF certification ratings should not be used for distribution.  In addition, potable water or in food processing.

Passing NSF Certifications?

Above all, use a valve that isn’t certified when you have an application that calls for an NSF certification. Also, this is not a good approach will not pass state and federal inspections, and is simply against the law.

What are NSF Certifications?

NSF stands for the  National Sanitation Foundation.  When a valve, fitting, or pipe is NSF-certified, it meets or exceeds particular standards.  Finally, 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 media.  Also, many relate to commercial and residential plumbing.  Others are for pharmaceutical safety, etc. Moreover, the point is if the valve you want to purchase and use in your application does not carry NSF certifications.   Furthermore, if the application 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 lawsuits.  Also, 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 that would have to be immediately replaced.

Identifying NSF Certification

Most manufacturers 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. Also, others will let you know which valves are not certified.

In conclusion, if NSF certifications aren’t mentioned on the manufacturer data sheet, it’s best to contact them directly. 

NSF Certification

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.
