BS EN 13709 Check Valve

A BS EN 13709 check valve (more precisely classified under British and European standards as a steel globe stop and check valve) is a dual-function, linear-motion non-return valve manufactured and pressure-tested in compliance with BS EN 13709. Featuring a spring-assisted disc, it automatically closes against backflow under normal operations, but can also be manually driven down via its rising stem and handwheel to mechanically lock the disc shut, functioning as a positive isolation valve. Conforming to European pressure equipment directives (PED) and standards like EN 1092-1, these high-integrity valves are primary specifications in high-pressure steam utility boilers, district heating plants, and chemical process bypass lines, allowing piping engineers to reduce valve footprints by importing certified BS EN 13709 stop-check valves directly from premier manufacturers in China via our advanced B2B commercial platform.
