High and medium pressure globe valve

High and medium pressure globe valve

Globe valve opening and closing parts are plug-shaped discs, the sealing surface is flat or tapered, the discs move linearly along the center line of the fluid. The movement of the valve stem can be lifted (the stem is raised and lowered, and the hand wheel is not raised and lowered), and there is also lifted and rotated (the hand wheel and the stem are raised and lowered together, and the nut is set on the valve body). The high and medium pressure globe valve is only suitable for full open and full close, and it is not allowed to adjust and throttle.
