EN 13709 Check Valve

An EN 13709 check valve (more precisely defined under European standards as a steel globe stop and check valve or non-return valve) is a multi-functional, dual-purpose linear-motion valve designed to regulate flow and automatically prevent fluid backflow in high-pressure industrial piping networks. Engineered, manufactured, and pressure-tested in strict compliance with European Norm EN 13709, this valve features a spring-loaded disc that automatically closes against the seat when upstream flow stops, acting as a high-integrity non-return check valve. When the handwheel or actuator is manually engaged, the stem can be driven down to lock the disc in place, transforming the unit into a tight-shut-off globe isolation valve. These safety-critical valves are essential specifications in high-pressure steam utility boilers, chemical processing lines, and district heating networks operating under European design directives, allowing plant operators to simplify piping layouts and reduce valve counts by importing certified EN 13709 stop-check valves directly from specialized manufacturers in China via our advanced B2B commercial platform.
