Triple eccentric butterfly valve with pneumatic actuator

Because of the high-quality components that go into its construction, the Triple eccentric butterfly valves with pneumatic actuators that GMK offers have excellent performance in the areas of flow control, sealing, and longevity. Triple offset valves are typically utilized in settings that call for a tight shut-off in both directions, such as in the oil and petroleum industry, chemical manufacturing facilities, shipbuilding, and terminals and tanks. Additionally, they are utilized for unclean or heavy oil to prevent the oil from extruding. It has a soft seal that prevents any leaking from occurring. It has a long service life and excellent sealing performance, among its many other features.

  • Body type:Straight-through type
  • Bonnet type:Standard integral type
  • Flow characteristic:Approximately equal percentage
  • Pressure class:PN1.6, 4.0, 6.3Mpa(ANSI 150, 300, 600LB)

It is able to perform admirably at both hot and low temperatures, which are typical in-service conditions. Additionally, they are utilized for unclean or heavy oil to prevent the oil from extruding.



  • The metal hard seal has an easier time starting up thanks to the one-of-a-kind design of the triple eccentricity.
  • It can be used during the process of installing as well as removing the valve.
  • It can withstand high temperatures, is not easily corroded, and is very durable.
  • The opening torque is not very high.
