API Tilting Disc Swing Type Check Valve
Tilting Disc Check Valves consist of a cylindrical housing, with a pivoted circular disc. The pivots are located just above the center of the disc, and offset from the plane of the body seat. This design gives a bell-crank action to the disc. The seat is of circular bevel type and the disc drops in or out of contact without rubbing or sliding.
Futures:
1, Reduced maintenance is assured because the disc is the only moving part and is designed to minimize flutter in the closed position, thus reducing wear on the pivot pin, disc, and seat.
2, Loss of head is minimized by the balanced disc and its "aerofoil" design. Streamlined body without pockets contributes to straight-through flow.
3, Short distance of travel, combined with a balanced disc allows rapid closure while minimizing slamming.
4, Drop tight seating is accomplished over the full pressure range because a slight clearance at the pivot pin assures complete seating between the disc ring and body ring.
