Advantages Of Flat Gate Valves

The flow resistance is small, and the flow resistance of the non-shrinking mouth is similar to the flow resistance of the short tube. The flat gate valve with diversion hole can also be directly pigged with the pig when installed on the pipeline. Because the gate is sliding on the two seat surfaces, because the flat plate gate valve fluid can be applied to the medium with suspended particles, the sealing surface of the flat plate gate valve is actually automatic positioning. Seat sealing face is not damaged by thermal deformation of the valve body. Thermal elongation of the stem does not overload the sealing face even when the valve is closed in a cold condition. At the same time, when the valve is closed, the flat gate valve without diversion hole does not require the closing position of the gate plate to have a high precision, so the electric flat valve can be used to control the opening and closing position of the stroke.
