GA Figure 251, 252

Size: 3" to 48"
Type: Check Valve

GA Industries Figures 251-DS and 252-DS heavy duty, customizable swing check valves utilize an adjustable counterweight for rapid closure combined with a highly engineered air cushion chamber to provide non slam operation.In addition, the valve's outlet connection is expanded one or two sizes larger than the inlet connection which can often eliminate the need for an increaser fitting on the pump discharge. __Typically installed on the discharge of a pump to prevent backflow when the pump is off line, it opens smoothly at pump start and closes quickly and quietly upon pump shutdown. __The Figures 251-DS and 252-DS meet the design, materials of construction and testing required by AWWA C508 and are suitable for use with water or sewage.
