Description
Figure 221-DS Increasing Size Lever & Weight Swing Check Valve
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.
