DESIGN FEATURES

  • Design standard as per: API 609, ASME B16.34, GB/T12238, JB/T 8527.
  • Small installation space, light weight, and maintenance friendly;
  • Good sealing effect and long service life;
  • Simple structure and small opening/closing torque;
  • Good flow adjusting ability, high precision of flow characteristic curve and good dynamic adjustment stability;
  • For soft seat the leakage rate: ANSI B 16.104 Ⅵ.

For the structure of the triple-eccentricity seal butterfly valve, when the valve is in the completely open state, its butterfly plate sealing face will break away from the valve seat sealing face completely; when it is opened from 0 to 90°, the butterfly plate sealing face will break away from the valve seat sealing face upon opening; when it is closed from 90° to 0°, and only upon closing, the butterfly plate sealing face can contact and press onto the valve seat sealing face tightly.
