Proquip dual-plate check valves are made to handle an extensive range of applications. The inherent design of the Proquip dual-plate check valve results in significantly reduced weight when compared to conventional full-bodied swing check valves and can be as little as one fifth the weight of an equivalent full-bodied unit as valves increase in size. This results in savings in initial cost, space and pipe support element installation.

SN offers swing check valves in DN 50-600 with lever and weight, lever and spring or with closed bushings. SN swing check valves feature very easy access to maintenance and can be installed in both horisontal and vertical positions.
