Stainless Steel Sanitary Check Valves

What is the sanitary check valve?

Sanitary check valves also known as one-way valves, their roles are to prevent the pipeline water back in the media. They are specifically used for the food handling and processing industries to prevent backflow of product. Commonly used with liquid products, spring check valves are designed to assist closure pressure to create a positive shutoff.

Sanitary check valves are different from many other types of valves, for ss check valves work automatically and most are not controlled by a person or any external control. Accordingly, most do not have any valve handle or stem. Thus there is an important concept in hygienic check valves, it is, the cracking pressure. Cracking pressure is the minimum upstream pressure at which the valve will operate. So the check valve is designed for and can, therefore, be specified for a specific cracking pressure.
