Steriflow Sanitary / Hygienic Check Valve Innovations
Steriflow developed the industry’s first check valve specifically for installation in WFI and BioProcess lines.
- Our SVC and SHC Series sanitary non return valves were designed without sliding stems and springs, eliminating the crevices and particulate generation associated with traditional “sanitary” spring-loaded check valves.
- Steriflow also developed the world’s first (and only) BioProcess drain line check valve. Designed for installation in vertical down-flow drains, it continuously drains process waste without creating a dead-leg. If liquid backs up in the line below the check valve, it closes to prevent upstream contamination.

Applications of Sanitary Check / Non Return Valves
Sanitary check valves are essential components in industries where hygiene, safety, and process integrity are critical. Common applications include:
- Food and Beverage Processing: Used to prevent backflow of liquids and cleaning agents, helping maintain hygienic production standards.
- Pharmaceutical Manufacturing: Designed to support sterile operations by preventing cross-contamination and maintaining clean process lines.
- Biopharmaceutical and Medical Industries: In bioprocessing and biopharmaceutical environments, check valves ensure consistent, contamination-free flow. Crevice-free designs are especially important in these sensitive applications, as they support cleanability and process integrity.
