Description

The valve is small in size and light in weight. It can be used as a device to cut off and regulate flow in various medium pipelines. By choosing valve plates and seals of different materials, as well as pinless connections between plates and shafts, it can be used in worse working conditions, such as desulfurization, vacuum, seawater desalination system, etc. The butterfly valve with lug-to-clip can repair the downstream pipeline and equipment of the valve on-line, and the valve can repair the downstream pipeline and equipment on-line, and the valve can be installed at the end of the pipe as an exhaust valve.
