Double Disc Check Valve

8 products found

A double disc check valve (dual-plate check valve) is an automatic, high-efficiency non-return valve engineered with two semi-circular plates pinned to a central hinge shaft. Its compact wafer or lug body slides directly between piping flanges, significantly reducing structural footprint and weight compared to bulky swing check valves. When forward line pressure exceeds the cracking threshold, the two plates fold inward along the central pin, creating a streamlined, symmetrical flow profile that lowers pressure drop and fluid turbulence across high-velocity streams. The dual plates utilize a torsion spring assembly that forces them closed the moment forward fluid velocity decelerates, sealing tightly against an elastomeric or hardfaced metal seat before flow reversal occurs. Piping engineers and heavy-industrial procurement networks can eliminate water hammer surges and minimize line pressure drops by importing certified double disc check valves directly from leading manufacturers in China via our advanced B2B commercial platform.
