Butterfly Check Valve

12 products found

A butterfly check valve (commonly referred to as a dual-plate check valve or double-disc check valve) is a compact, automatic non-return valve featuring two semi-circular plates hinged around a central pivot pin within the flow stream. Driven entirely by fluid kinetics, forward line pressure pushes the two spring-loaded plates forward, folding them together like a pair of wings to clear the flow path. When the flow decelerates or reverses, the internal torsion spring instantly snap the plates back onto a resilient or metal-to-metal seat, sealing the line before flow reversal can occur. This dual-plate geometry significantly reduces the closing distance and disc weight compared to traditional single-plate swing check valves, effectively eliminating water hammer and severe pressure surges. Procurement managers and marine piping engineers can secure absolute mechanical compliance and reduce maintenance overhead by importing certified butterfly check valves directly from premier manufacturers in China via our advanced B2B digital marketplace.
