Features of  API bellows gate valve

The opening and closing part of the bellows gate valve is a plug-shaped valve disc, the sealing surface is flat or conical, and the valve disc moves linearly along the centre line of the fluid. The movement form of the valve stem includes a lifting rod type (the valve stem is raised and lowered, the handwheel does not rise), and there is a lifting rotating rod type (the handwheel and the valve stem rotate and rise together, and the nut is set on the valve body). The bellows gate valve is only suitable for fully open and fully closed, adjustment and throttling are not allowed. This type of valve should generally be installed horizontally in the pipeline.

The valve stem of the gate valve adopts a double sealing structure of bellows and packing to ensure a leak-free seal at the valve stem. It is used in power stations, natural gas, ammonia, vacuum, refrigeration systems, hot oil, and hot water systems, and is especially suitable for flammable and explosive, Toxic and precious media pipelines.
