BS 5352 Check Valve
103 products found
A BS 5352 check valve is a compact, high-integrity forged steel non-return valve manufactured in strict compliance with British Standard BS 5352 for small-bore piping networks (typically NPS 2 and smaller). Designed to handle severe high-pressure, high-temperature service in downstream refineries, chemical plants, and steam lines, this standard mandates precise wall thicknesses and strict non-destructive testing benchmarks to eliminate porosity defects common in casting. Its responsive, spring-loaded piston or heavy swing disc reacts immediately to flow reversal, protecting upstream pumps and instruments from dangerous water hammer or backflow surges. Our digital marketplace connects global procurement teams with premier manufacturers in China who produce certified BS 5352 check valves, offering an extensive selection of forged carbon, stainless, and alloy steel configurations with threaded, socket-weld, or flanged ends.
