GA Figure 221, 222 Heavy Duty Swing Check, Lever & Weight Increasing Size

See data sheet for sizing

Productgroup: Check Valves

Medium: Water,  Wastewater

VAG GA Industries Figures 221-DS and 222-DS are heavy duty, customizable swing check valves that utilize an adjustable counterweight assisted closure to minimize slam and hammer. In addition, the valve’s outlet connection is expanded one or two sizes larger than the inlet connection which can eliminate the need for an increaser fitting on the pump discharge.

Normally installed in 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.

Figures 221-DS and 222-DS meet the design, materials of construction and testing required by AWWA C508 and is suitable for use with water or sewage.
