Flat Gate Valve Slab Gate Valve 150lb WCB

The flat gate valve is a sliding valve whose closing part is a parallel gate. The closing part can be a single gate or a double gate with a spreading mechanism in between. The pressing force of the gate to the valve seat is controlled by the medium pressure acting on the floating gate or the floating valve seat.
Its advantage is that the flow resistance is small. The flat gate valve with diversion hole is installed on the pipeline, and the pig can be used for pigging directly. Since the gate plate slides on the two valve seat surfaces, the flat gate valve fluid can be applied to the medium with suspended particles, and the sealing surface of the flat gate valve is actually automatically positioned. The seat sealing surface will not be damaged by thermal deformation of the valve body. And even if the valve is closed in a cold state, thermal elongation of the valve stem will not overload the sealing surfaces. At the same time, when the valve is closed, the flat gate valve without the diversion hole does not require high precision in the closing position of the gate, so the electric flat valve can use the stroke to control the opening and closing position.
