Manual Butterfly Valve

Butterfly valve is a common industrial pipe valve, its simple structure, small size, light weight, quick switching, low fluid resistance, is widely used in various industrial fields. The main characteristic of the butterfly valve is that the opening of the valve is directly proportional to the fluid resistance inside the valve, so it can be used to regulate the flow in the pipeline.
