Bronze Wafer Check Valve

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.

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 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.

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.
