BS 5352 Ball Valve

A BS 5352 ball valve is a small-bore, high-pressure forged steel quarter-turn valve manufactured in strict accordance with British Standard BS 5352 (often updated or integrated with ISO 15761) to deliver bubble-tight isolation in demanding utility networks. Typically constructed from robust forged carbon steel (such as ASTM A105) or forged stainless steel (such as ASTM A182 F316) in sizes up to 2 inches, its heavy-duty forged construction eliminates the porosity defects common in castings, ensuring superior grain structural integrity under intense thermal and mechanical stresses. The internal spherical ball rotates 90 degrees against high-purity polymer seats like PTFE for tight ambient sealing, or against hardfaced metal-to-metal seats for high-temperature services, while its blowout-proof stem design guarantees absolute field safety during operation. Piping contractors and power plant procurement managers can secure code-compliant, high-pressure isolation by importing certified BS 5352 ball valves directly from specialized manufacturers in China via our advanced B2B commercial platform.
