Bronze Wafer Check Valve

The seat sealing surface of the Rubber Lined Check Valve can be used as body hardfacing material or lining rubber, which has wide application range and reliable sealing. For industrial, environmental protection, water treatment, high-rise building water supply and drainage pipeline, to prevent the reverse flow of media. The Rubber Lined Check Valve plate is two semicircle, and the spring is forced to reset. Because the force of the torsion spring usually is closed, when the fluid is moving forward, the pressure of the fluid turns the disc to turn around the hinge and the valve opens. Once the fluid flow stops, the valve is closed before reverse flow due to the action of the spring.

The Wafer Lift Check Valves consists of valve body, disc and spring. It is installed horizontally or vertically in the pipeline system to prevent the media from backstreaming. The valve has the advantages of short structure, small volume, light weight, quick closing of disc, small water hammer pressure, smooth flow passage, small fluid resistance, sensitive action and good sealing performance.

KOSEN Wafer Type Flange Check Valve has retainer and retainer-less type design. Dual plate check valves have the advantage of zero leakage toward outside, cost saving. It can be installed in any line orientation, superior seal performance. Valves are designed in accordance to API 594 and have dual plate or single plate design and pin can be retainer-less type.

KOSEN Wafer Single Disc Swing Check Valves has short structure length, small size, light weight, fast closure of valve disc, small pressure of water hammer, convenient installation, small fluid resistance, sensitive movement, good sealing performance, short stroke and small impact force of the valve, the whole structure, simple compact, long service life, high reliability and so on.
