The opening and closing part of the fluorine lined globe valve is a plug shaped valve disc, with a flat or conical sealing surface. The valve disc moves in a straight line along the centerline of the fluid. The movement forms of the valve stem include the lifting rod type (valve stem lifting, handwheel not lifting), as well as the lifting rotating rod type (handwheel and valve stem rotating together to lift, nut installed on the valve body). Globe valves are only suitable for fully open and fully closed, and are not allowed to be adjusted or throttled.
