Design Features
  • Full diameter structure, to ensure the flow area of the valve, to see the flow resistance when the fluid through the valve
  • The butterfly plate adopts butterfly streamline design, which can ensure the stress intensity of the center of the butterfly plate, and also ensure that the valve can obtain a large flow coefficient and a small fluid resistance coefficient
  • Simple structure, small flow resistance
