Steel & O’Brien’s wide range of stainless steel sanitary check valves help make sanitary simple for you and your operations. We manufacture these in a variety of sizes and pressure ratings, with multiple capabilities to help them fit into virtually any scenario you may have. These are critical for protecting your pumps and other valuable equipment from backflow caused by sudden pressure changes in your pipes.

These versatile valves are used across numerous sectors where preventing reverse flow is essential. The most prominent examples of industries that rely on these are the food and beverage and pharmaceutical sectors. Sanitary check valve types include ball, disc, and air-blow configurations. Ball check valves use an internal ball that moves away from the seat during forward flow and returns to the seat to prevent reverse flow. For a closer look at the operating mechanism, flow characteristics, and CIP considerations, learn how sanitary ball-type check valves work. Disc-type check valves use a spring-loaded plunger or disc to control flow direction. Air-blow check valves are designed for applications where compressed air is introduced into sanitary process systems.

Choosing the right check valves for your specific application means understanding the unique standards of your industry, as not all sanitary valve products are suitable for every use. You also should pay close attention to the compatibility of the materials used in their manufacture and any chemicals you use in your processes. A sanitary check valve also may be damaged if it is used at temperatures or pressures it was not designed to withstand. Depending on your infrastructure, you also may require a sanitary fitting that is compatible with clean-in-place equipment.
