Stainless Steel Sanitary Check Valve
Sanitary Check Valves are anti-backflow devices designed for high-purity industries like food, pharmaceuticals, and biotechnology. Constructed with stainless steel check valve bodies using 316L or 304 stainless steel, they offer corrosion resistance, high-temperature tolerance, and smooth mirror/electropolished surfaces to ensure hygienic, residue-free cleaning, complying with food safety standards.
These valves support flange, tri-clamp, welded, and union connections for diverse piping systems. Flange connections suit high-pressure or large-diameter applications with robust sealing; tri-clamp connections enable quick disassembly for frequent cleaning; welded connections provide leak-free permanence for sterile fluids; Union connections simplify installation with flexibility and easy maintenance.
Featuring a spring-assisted sealing mechanism, they automatically open/close via media pressure differentials, preventing backflow contamination. The smooth internal flow path accommodates liquids, gases, and particle-laden media, with a broad operating temperature range (-20°C to 150°C). Sanitary stainless steel check valves ensure unidirectional flow, low resistance, and long-term reliability, enhancing production safety in critical hygiene-sensitive processes.
