Tilting Disc
Size:
6" to 36"
Type:
Check Valve
The GA Industries Tilting Disc Check Valve features a streamlined design and full flow area for lower head loss than conventional swing check valves.Its energy efficient operation is combined with a short 40-degree disc stroke that provides quick closing to minimize hammer.The valve employs offset seating technology to smoothly lift the disc off of the seat during opening and into the seat during closing without binding or sticking. __If flow reversal occurs, the offset disc design divides the disc so that hydraulic forces acting on the upper third of the disc counteract the forces acting on the lower two thirds for an inherent cushioning effect. __The bottom buffer is a hydraulic dashpot that further minimizes hammer by decelerating the final 10% of the disc's closure in situations where rapid flow reversal occurs, such as multiple pumps and/or short pipes.
