Steriflow Sanitary / Hygienic Check Valve

Steriflow developed the industry’s first check valve specifically for Water for Injection (WFI) and bioprocess lines.

The SVC and SHC Series feature a springless design that eliminates springs, sliding stems, and hinges, reducing potential particle entrapment and shedding.

Designed to ASME BPE guidelines, these sanitary check valves support Clean-in-Place (CIP), Sterilization-in-Place (SIP), and autoclaving.

Steriflow Sanitary Check Valve Series

SHC Series – Horizontal Flow

Designed for horizontal process lines, the SHC Series features a fully drainable body without flat horizontal wetted surfaces and offers multiple disc options.

Sizes: 1/2″-2″ (DN15–DN50)

SVC Series – Vertical Flow

SVC Up-Flow: Designed for vertical up-flow applications with Teflon, PEEK, and stainless steel/EPDM disc options.
SVC Down-Flow: Designed for liquid outlet and drain applications. Its floating disc prevents backflow and eliminates dead legs to help minimize contamination risks.

Sizes: 1/2″-4″ (DN15–DN100)

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:

Pharmaceutical and Biopharmaceutical Manufacturing: WFI systems, purification, and high-purity fluid transfer.
Bioprocessing: Media and buffer preparation, process fluid distribution, and drainage.
Food and Beverage Processing: Hygienic production lines requiring reliable backflow prevention.

What Is a Springless Check Valve?
A springless check valve prevents reverse flow without using a spring to operate its disc. This design helps reduce crevices and potential sources of particulate generation in applications where process cleanliness is critical.
