Rubber lined butterfly valve with pneumatic actuator

GMK has a rubber-lined butterfly valve with pneumatic actuator that utilizes a structure that is rubber-lined throughout the central line cavity. To effectively prevent corrosion of the valve caused by media, the body and disc are lined with synthetic rubber, or the body is lined with rubber such as EPDM, NBR, and the disc is made of high-quality alloy steel, Stainless steel, or UB6 904l, amongst other materials. This valve has a characteristic called bubble-tight that assures a great seal by limiting linear movement and providing exceptional reliability over thousands of cycles. This feature also gives excellent durability. This valve has a working temperature range that goes from -30 degrees Celsius to 180 degrees Celsius.

  • 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)

GMK is a well-known firm that offers a wide variety of valves of excellent quality. The rubber-lined butterfly valve with a pneumatic actuator is qualified for both gaseous and liquid services. They have improved resistance to corrosion and higher durability overall. It performs quite well in terms of sealing. The butterfly valve is extensively used because it is a great option to control and shut off applications of water, air, petroleum, and other fluids. This valve can be found in a wide variety of applications.


  • It has a lugged body design that offers a solution that is more economical for services that are not important.
  • Our rubber-lined butterfly valves provide a solution for high-pressure applications that is not only lightweight but also cost-effective, heavy-duty, and requires no maintenance.
  • The pressure ratings of butterfly valves with rubber lining are lower, but their performance is higher.
  • They can be installed and removed without causing any displacement to the pipe system.
