1. The flanged butterfly valve requires only a few parts due to its small size and light weight.
2. The operation is simple, only need to rotate 90 ° to close
3. It is with good fluid control characteristics, the pressure generated by the pipeline can be reduced after pass the valve
4. Sealed in both directions
5. Easy to repair and care, and can be installed at will
6. The driving method can be selected from manual, electric and pneumatic
7. The outer circle of the butterfly plate adopts spherical shape, which greatly improves the sealing performance and prolongs the service life of the valve

widely used in gas, oil, water, chemical engineering and other related industries, also in cooling water systems of thermal power stations
