Rubber Flap Swing Check Valve German Stand Ductile Iron GGG50/GGG40/QT450/QT400  PN16 DN150(SFCV)For Water Gas Oil

product description

The check valve is a valve used to prevent the backflow of the medium, the reverse rotation of the pump and the driving motor, and the discharge of the medium in the container. The check valve is an automatic valve, which automatically opens and closes the valve flap depending on the flow of the medium itself.

The silent check valve is a noise reduction structure added to the check valve to eliminate the sound of fluid hammering and the operation sound of the valve disc hitting the valve body. Silent check valves include spring return check valves and flap check valves. The flap-type check valve in the prior art is usually covered with a rubber layer on the flap of the flap, and the operation sound of the check valve is reduced by using the rubber layer.

However, in the existing flap check valve, the flap disc covered with a rubber layer has a relatively heavy weight. When it is used for a period of time, especially when the temperature difference changes greatly and the working conditions are poor, the flap disc covered with the rubber layer is relatively heavy. The flap valve disc is easy to age and deform, which causes the check sealing effect of the flap valve flap to deteriorate, which affects the performance of the flap type check valve.
