The opening and closing part of the angle globe valve is a plug-shaped valve disc, the sealing surface is flat or conical, and the valve disc moves linearly along the center line of the fluid. The movement form of the globe valve stem includes the lifting rod type (the valve stem rises and falls, the handwheel does not rise and fall), and the lifting and rotating rod type (the handwheel and the valve stem rotate and rise together, and the nut is set on the valve body). The bellows globe valve is only suitable for fully opening and fully closing, and adjustment and throttling are not allowed.
