Product Description

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.
