Wafer Type Flange Check Valve

KOSEN Inner Wafer Dual Plate Check Valves are suitable for using on various kinds of pipeline from Class150 To Class2500, PN20 To PN420 to cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc.

KOSEN Cast Steel Lug Wafer Dual Plate Check Valves has retainer and retainerless type design. Dual-disc 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 disc or single disc design and pin can be retainerless type.

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 Cast Iron Wafer Check Valves is made by foreign advanced structural design in our factory, which is in line with relevant national standards and belongs to energy saving products. This product has good check performance, safety and reliability, and low flow resistance coefficient. It is mainly used in petroleum, chemical industry, food, medicine, textile, paper making, water supply and drainage, smelting and energy system.
