Triple eccentric butterfly valve

  • The yoke is designed according to ISO5211, which is convenient for installing gearbox, pneumatic or electric actuator.
  • Anti-valve stem blowout design
  • low leakage packing (optional), advanced metal-bonded graphite packing (for the bottom and top ) and low leakage packing (for the middle) to ensure a maximum leakage no less than 20ppm
  • Extend the bearing design, the use of long precision bearings, reduce valve stem friction, to ensure low operating torque, graphite ring is used to prevent pollutants from entering the bearing
  • Multi-layer seal design, elastic deformation of the seal ring can guarantee zero leakage, the seal ring is truly interchangeable, convenient maintenance
  • The valve seat surfacing hard alloy, the overall hardened valve seat, extending the life of the valve, reducing the number of maintenance.
