Sanitary check valves are used to prevent backflow contamination in pipelines. These valves are used in manufacturing processes & other applications with stringent hygiene standards, such as the food, beverage, pharmaceutical, chemical, and medical industries. In this article, we’ll dive deeper into how exactly sanitary check valves prevent backflow contamination!

Check Valves vs. Sanitary Check Valves
Check valves are valves that only allow liquid and gasses to flow through them in one direction. Check valves achieve this one-way flow by employing the force of the liquid or gasses flow to automatically engage or disengage the stopping mechanism in the valve. Check valves have two ports; one for liquids or gasses to enter, and one for them to exit. When fluid flows forward, the valve automatically opens to let the fluid flow through, however when fluid attempts to reverse direction and flow backwards, the check valve will automatically close and prevent backflow contamination. Check valves have a relatively straightforward design and typically do not require any external controls, as the flow of the fluid within the pipeline does all the engaging and disengaging automatically.
The primary differences between an average check valve and a sanitary check valve are the design and materials used to create them. The inside portions of sanitary check valves that come in contact with the liquids or gasses within the pipeline are typically made from either 304 or 316 stainless steel, both of which are non-toxic and corrosion-resistant. Sanitary check valves also have polished, easy-to-clean surfaces in order to prevent build-up of the medium flowing through them.
