Hard Seal Pneumatic Flange Three Eccentric Butterfly Valve

Three eccentric butterfly valve is widely used in metallurgy, electric power, petrochemical industry, water supply and drainage, municipal construction and other industrial pipelines with medium temperature ≤ 425 ℃, for regulating flow and breaking fluid. Normally material: cast iron, cast steel, stainless steel. If the stem axis deviates from the disc center and the body center at the same time, and the rotation axis of the valve seat has a certain angle with the channel axis of the valve body, it is called three eccentric butterfly valve

  • Model: HK59-D-GF
  • Size Range: 2''~18''
  • Pressure Range: 1.0MPa to 2.5MPa
  • Material: Stainless Steel

    COVNA HK59-D-GF Pneumatic three eccentric butterfly valve, the valve body part adopts three eccentric structure, the valve plate and sealing mechanism are unique in design, with excellent cutting performance and durability, as well as dual functions of cutting and adjusting. It is small in size, light in weight, economical and practical, and easy to maintain; Low friction, high efficiency, high thrust and good safety; Simple, eye-catching, reliable and integrated travel indication, combined installation of limit switch and solenoid valve, no external pipeline, reducing leakage point; It can realize bidirectional sealing function, which can be adjusted and cut off

    A variety of actuator forms are available for selection to meet the requirements of different users; The design of flexible and combined actuator (manual mechanism) can ensure the free installation and flexible control in all directions
