The environmentally friendly butterfly valve is a valve device that is characterized by simple structure, small size, light weight, convenient operation, easy maintenance, and certain resistance to chemically corrosive media. The environmentally friendly butterfly valve adopts a top-mounted structure, which reduces the connecting bolts of the valve body itself under high-pressure and large-diameter conditions, enhances the reliability of the valve and can overcome the impact of the system's own weight on the normal operation of the valve.

The sealing principle of butterfly valve is to use sealing gasket to seal the medium, which has good sealing performance. The sealing gasket can be made of corrosion-resistant materials, so that the butterfly valve has a certain resistance to chemically corrosive media. Moreover, with the application of polymer materials, butterfly valves have higher requirements for corrosion resistance.

Environmentally friendly butterfly valves are widely used in pipelines such as coal chemical industry, petrochemical industry, rubber, papermaking, pharmaceuticals, etc. as a diversion and confluence or flow direction switching device for media. Due to its excellent performance, butterfly valves have broad application prospects in many fields.
