Wafer Type Flange Check Valve

KOSEN Hub Type Dual Plate Check Valves is an important mechanical device in the pipeline. It controls and controls the pressure, flow and direction of the equipment and piping through valve opening and closing. Valve classification is a lot, check valve is to rely on the flow of the medium itself to automatically open and close the valve, allowing the medium unidirectional flow valve, protecting pipe machinery from water hammer damage play an important role. The instantaneous impact pressure of water hammer in the working process of the check valve may be several times higher than that of the normal working pressure. It has a great influence on the performance stability and reliability of the system. The water hammer problem of the check valve is more prominent, and the water hammer problem in the pipe is more prominent, in order to prevent the water hammer in the pipeline, and the design of the check valve is designed in the design of the check valve. Some new structures and materials are used to ensure the working characteristics of the check valves and minimize the impact of the water hammer.

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.

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.
