Half PTFE Lined Butterfly Valve

Separating the stream or controlling it may be accomplished with the help of GMK-lined butterfly valves.  The disc, which is in the middle of the throttle body, serves as the actuator for shutting the valve. To the shaft, which originates at the disc and travels up through the head of the valve body, the discs are linked to an implement or control. GMK is an emerging brand of high-quality valves. We offer various types of valves on our website. In situations with restricted space, butterfly valves are often employed. You can use our GMK Half  PTFE Lined Butterfly Valve in both the completely open and fully closed positions, in addition to being utilized for flow regulation and throttling.

Product name: Half PTFE Lined Butterfly Valve

The layout of GMK half PTFE lined Butterfly valves is straightforward, and they need just a little amount of routine maintenance. They are simple to set up and manage once they are in place. In addition, the price for a butterfly valve of the same size is often substantially lower than the price for a ball valve of the same diameter. Our valves do not need a great deal of torque to function well, and their operation may be automated to make them more energy efficient.


  • Leisure time is cut down thanks to the standard lining on both the body and the disc, which protects against the most harmful materials.
  • Availability and high versatility are made possible by the provision of a wide variety of metal discs that may be used in situations that call for a higher level of safety.
  • Enhanced abrasion resistance in situations with temperatures up to 90 degrees Celsius thanks to the wheel and body.
