The valve can be widely used in the clean water system of municipal pipe network, water heating system, construction and other industries. It can not only quickly connect or cut off the medium, but also quickly adjust the medium flow. The valve can be used on the pipeline or equipment of 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
