Description

A dual-plate wafer-type check valve with an aluminium bronze body and Monel disc and stem, designed for backflow prevention in systems handling corrosive media such as seawater, brine, or chemical solutions. Two spring-loaded plates open under forward flow and close rapidly upon flow reversal to prevent water hammer and back-pressure damage. The wafer construction allows installation between standard flanges and supports both horizontal and vertical upward flow orientations.
