The opening and closing member of the high pressure shut-off valve is a plug-shaped valve flap having a flat or tapered surface, and the valve flap moves linearly along the center line of the fluid. The movement form of the valve stem has a lifting rod type (the valve stem is lifted and lowered, the hand wheel does not move up and down), and there is also a lifting rotary rod type (the hand wheel and the valve stem rotate together and the nut is set on the valve body). The shut-off valve is only suitable for full opening and full closing, and adjustment and throttling are not allowed.
