Triple Eccentric Butterfly Valve With Pneumatic Actuator

GMK Triple Eccentric Butterfly Valve With Pneumatic Actuator crams a significant amount of functionality into a very tiny size. It is easy to use, and in comparison to similar products on the market, it has a lower torque. This is the product to utilize when you really cannot afford to lose even a single point. The design of the triple offset valve allows for the achievement of zero leakage on metal-to-metal contact. Because the hard-facing seat prevents any rubbing from occurring between the seat and the seal ring along the flow channel, the cycle life is significantly increased. It is possible to open and close it quickly and often because of the reliable sealing it provides.

The design of the Triple Eccentric Butterfly Valve With a Pneumatic Actuator incorporates the triple-eccentric structure into its overall layout. There is no friction between the disc and seat over the whole travel range of the disc opening and closing. The sealing face of the seat is a composite material consisting of metal and nonmetal, which reflects the multilayer design of the seat. It is unaffected by either high or low temperatures, both while it is operating and when it is not. The butterfly valves of the 70D00 Series are renowned for their high degree of sealing performance as well as their exceptional longevity. In an industrial environment, it is possible to utilize it for the control and cutoff of almost any gas or liquid.


  • When it comes to the structure and materials used in valves, there is a diverse selection of options available for usage in a variety of systems. 
  • It is well-known for the high standards of flow and control they provide, as well as for its ability to seal completely and its dependability in the face of harsh circumstances. 
  • It is perfect for use in situations where there should be as little leakage as possible. 
  • Triple valve is hard-facing metal-to-metal valves, as opposed to soft-facing plastic-to-metal valves.
