This valve is small in size and light in weight. It can be used as a device for cutting off and regulating the flow of various media in pipelines. By selecting different materials for the valve plate and sealing seat, as well as through the connection without pins between the plate and the shaft, it can be used in more harsh working conditions, such as desulfurization, vacuum, and seawater desalination systems. The lug-welded butterfly valve can achieve on-site repair of the downstream pipeline and equipment of the valve, and this valve can also be installed at the pipe end to be used as an exhaust valve.
This valve is applicable in pipelines of systems such as petroleum, chemical engineering, food, medicine, papermaking, hydropower, ships, water supply and drainage, smelting, energy, etc. It can be used as a regulating and throttling device on various pipes and containers of corrosive and non-corrosive gases, liquids, semi-fluids, as well as solid powders.
