316L Stainless Steel Clamp-On Hygienic Weldable Check Valve

Cematic's 316L stainless steel clamp-on hygienic weldable check valve is designed to ensure efficient unidirectional flow in demanding sanitary systems.

Thanks to its detachable body with a clamp connection and Viton seat, it offers a quick, secure, and easy-to-maintain connection. Therefore, it is the preferred solution in the food, pharmaceutical, cosmetic, and chemical industries, where backflow control and hygiene are non-negotiable requirements.

Main Benefits:

• Total backflow prevention: Automatically closes when flow stops. Consequently, it protects equipment and piping from damage due to fluid return and cross-contamination.
• All SS316L construction: Body, disc, and spring in 316L stainless steel. Therefore, it offers high corrosion resistance and compatibility with food and pharmaceutical products.
• High-performance Viton seat: Resists temperatures up to 180 °C and a wide range of chemicals. In addition, it ensures a tight and durable seal even in extreme conditions.
• Detachable body with clamp connection: Allows disassembling the valve without special tools. Likewise, it facilitates inspection, cleaning, and seal replacement in the shortest possible time.
• Butt-weld ports: Eliminate leak points and dead zones in the piping. Consequently, they are ideal for CIP/SIP systems and aseptic processes.
• Compact hygienic design: No internal cavities where residues can accumulate. Therefore, it complies with the sanitary standards of the most regulated industries.

Applications

The weldable check valve (also known as a sanitary check valve) is used
primarily in systems where it is essential to prevent the reverse flow of liquids. Its design and materials make it ideal for sanitary applications. Below are some of its main applications:

Food and Beverage Industry: Prevention of backflow in production lines for milk, juices, beer, wine, etc.

Pharmaceutical Industry: In production lines for liquid medications, serums, or solutions. Meets high standards of cleanliness and chemical resistance.

Cosmetics and Personal Care: Production of creams, lotions, shampoos, where extreme cleanliness and non-reactive materials are required.

Steam or High-Purity Liquid Systems: Suitable for systems that transport clean steam, and/or purified water.
