Wafer Check Valve

The clamp lift check valve is a valve which is automatically opened and closed by the flow of the medium itself, and is used to prevent the reverse flow of the medium. It is also called a reverse check valve, a one-way valve, a countercurrent valve, and a back pressure valve. The check valve is an automatic valve. Its main function is to prevent the backflow of the medium, prevent the reversing of the pump and drive motor, and the discharge of the container medium. The check valve can also be used to supply pipelines where the pressure may exceed the system pressure. Check valves can be divided into swing check valves (with center of gravity rotation) and lift check valves (along the axis). Valves of this type should be installed horizontally in pipes.

GAIRUI 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.

GAIRUI Flanged 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. 

The function of the Bronze Wafer Check Valve is to control the one-way flow direction of the valve in the pipeline, so as to prevent the backflow of the medium in the pipeline. The check valve belongs to the automatic valve type, and the opening and closing part is opened or closed by the force of the flowing medium. Check valve is only used for one-way flow of medium pipeline, to prevent media backflow, in order to prevent accidents. It is mainly used in petroleum, chemical, pharmaceutical, fertilizer, power and other pipelines.

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.

The Wafer Single Disc Check Valves, also known as single check valve and check valve, is a valve which can automatically prevent fluid from backflow. The disc of the check valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the inlet side pressure is lower than the outlet side, the disc automatically closes under the influence of fluid pressure, gravity and other factors to prevent fluid backflow. It can be installed horizontally or vertically. The vertical installation should pay attention to the water flow from bottom to top. When installing, pay attention to whether the installation direction is correct.

GAIRUI 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 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.

GAIRUI Tilting Disc Wafer Check Valve, installed in the municipal, construction, steel, metallurgy, petroleum, chemical, food, medicine, power plant, water conservancy and irrigation and other fields of water intake, water supply, pressure, diving, sewage pumping room and oil, chemical fluid transportation system, melting electric valve, check valve and water hammer eliminator three equipment functions in one, It can effectively improve the safety and reliability of the system, meet the requirements of system automation control and energy saving.
