Sanitary Check Valves / Non Return Valves
Yuanzhou sanitary stainless steel check valves are designed to maintain one-way flow and prevent process media from flowing back into pumps, tanks, or upstream pipelines. Manufactured from 304 or 316L stainless steel, the valves are available in sizes from 1/2" to 6", with product-contact surfaces polished to Ra ≤ 0.5 μm for easier cleaning and reduced product buildup.
FDA-compliant EPDM, silicone, and FKM sealing materials are available for different media and operating conditions. Each valve undergoes 100% pressure and sealing inspection before shipment, making it suitable for food and beverage processing, dairy systems, pharmaceutical production, biotechnology, CIP lines, and other hygienic fluid applications.
