The valve is widely used in various pipelines of water supply and drainage, building fire protection and other systems, especially in the fire pipeline. The valve can be used on the pipeline or equipment with non corrosive medium to intercept, connect and regulate the flow
When the handle of the valve is rotated by 90 °, the valve shaft also rotates. The valve shaft drives the butterfly plate to rotate to open or close. The dial and the handle meet to adjust the flow
