What are the advantages of flat gate valves?

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