Advantages Of Flat Gate Valve

The flow resistance is small, and the flow resistance of the non-necked pipe is similar to that of the short pipe. The flat gate valve with diversion holes can be installed on the pipeline and can be directly cleaned with a pig. Since the gate slides on the two valve seat surfaces, the flat gate valve fluid can be suitable for media with suspended particles, and the sealing surface of the flat gate valve is actually automatically positioned. The valve seat sealing surface will not be damaged by thermal deformation of the valve body. And even if the valve is closed in the cold state, the thermal elongation of the valve stem will not overload the sealing surface. At the same time, when the valve is closed, the flat gate valve without a guide hole does not require a high accuracy in the closing position of the gate. Therefore, the electric flat valve can use the stroke to control the opening and closing position.
