This flanged dual-plate check valve delivers reliable, fast non-return performance with the convenience of bolted flange connections. A pair of spring-loaded half-plates hinged on a central pin opens under forward flow and closes simultaneously on a torsion spring when flow reverses, limiting slamming and water hammer. The flanged body provides a secure, fully retained installation, making it well suited to pump discharge, water treatment and general industrial process lines.
