Lug Type Check Valve

A lug type check valve is a compact, space-saving non-return valve featuring threaded bolt lugs surrounding its outer circumference, allowing it to be bolted directly between pipe flanges or dead-end installed at the end of a pipeline. Available in single-disc swing or dual-plate spring-assisted configurations, it automatically allows forward fluid flow and closes rapidly against backpressure, while its lugged body construction enables downstream pipe disassembly without draining the upstream system. Conforming to standards like API 594, ASME B16.34, and EN 593, these versatile non-return valves are primary specifications in chemical processing utilities, commercial HVAC cooling towers, and marine pumping systems, allowing piping designers to optimize space and maintenance flexibility by importing certified lug type check valves directly from premier manufacturers in China via our advanced B2B commercial platform.
