Bellows Gate Valve
The opening and closing part of the bellows gate valve is a plug-shaped valve disc, the sealing surface is a plane or a conical surface, and the valve disc moves linearly along the center line of the fluid. The movement form of the valve stem includes a lifting rod type (the valve stem rises and falls, and the handwheel does not rise and fall), and there is also a lifting rotating rod type (the handwheel rotates and lifts together with the valve rod, and the nut is arranged on the valve body).
