The PureMetix Sanitary Stainless Steel Check Valve is a high-performance, one-way fluid control component precision-engineered for high-purity applications in the food, beverage, dairy, and pharmaceutical industries. Fabricated from premium SS304 or SS316L stainless steel, this valve utilizes a spring-loaded disc mechanism that automatically opens when fluid pressure exceeds the spring tension and closes instantly when flow ceases or back-pressure occurs, effectively preventing backflow and protecting systems from damaging water hammer. Its hygienic design features a non-porous, mirror-polished surface finish that eliminates bacterial traps, making it fully compatible with Clean-in-Place (CIP) and Sterilization-in-Place (SIP) protocols. Available in sizes ranging from 1/2" to 4" and equipped with versatile Tri-Clamp, welded, or threaded connections, the valve is easily disassembled via a heavy-duty clamp for rapid maintenance and is available with multiple seal options including EPDM, Silicone, or Viton to meet various chemical and temperature requirements up to 120°C.
