JIS Check Valve

13 products found

A JIS check valve is an automatic non-return valve designed, manufactured, and pressure-tested in strict compliance with Japanese Industrial Standards, primarily JIS B2071 or JIS B2081. Engineered to automatically prevent fluid backflow, these valves rely on forward fluid velocity to lift the internal disc or swing plate, closing instantly via gravity or spring assistance when the flow decelerates. The JIS standard regulates specific pressure ratings expressed in nominal K-ratings (such as 10K, 20K, or 30K) rather than ASME classes, while standardizing precise face-to-face dimensions and flange configurations. Cast or forged from high-grade materials including cast iron, carbon steel, or stainless steel, JIS check valves undergo rigorous hydrostatic and pneumatic sealing protocols to ensure high-integrity isolation. Procurement managers and marine piping engineers can secure absolute mechanical compliance and reduce maintenance overhead by importing certified JIS check valves directly from premier manufacturers in China via our advanced B2B digital marketplace.
