BS 1868 Check Valve

A BS 1868 check valve is a robust, heavy-duty safety valve manufactured in strict compliance with the British Standard BS 1868 specification, which governs steel swing check valves for the petroleum, petrochemical, and allied industries. Designed to automatically permit fluid flow in a single direction and prevent backflow, this valve features a hinged swing disk (or clapper) that lifts entirely out of the flow path under forward pressure to minimize pressure drop and fluid resistance. It is engineered with a bolted bonnet for easy inline maintenance and constructed from high-strength cast carbon, alloy, or stainless steel to withstand severe high-pressure and high-temperature pipeline conditions. Think of us as your connection to a network of skilled China check valve manufacturers. We precision-engineer our BS 1868 check valves with rugged metal-to-metal seating and offer hard-facing options like Stellite for extra wear resistance—so you get dependable, low-maintenance backflow protection for your most critical energy projects.
