High-pressure flat gate valve with diversion hole is a valve device suitable for opening, closing and regulating the flow of control media in water, oil, mud and natural gas pipelines with working pressure ≤ 42MPa and working temperature ≤ 120°C. Flat gate valve has reasonable structure, reliable sealing and easy operation. The sealing surface is spray-welded with carbide, which has the advantages of anti-corrosion, wear resistance, erosion resistance, etc., and can be used for throttling. It is especially suitable for use as opening, closing and regulating devices to control the flow of media in water, oil, mud and natural gas pipelines with working pressure ≤ 42MPa and working temperature ≤ 120°C.
