GMK-lined balls have an isolating layer of material that prevents the medium from coming into touch with the valve body and maybe even the trim of the valve itself. The lining’s primary function is to prevent any corrosive damage that may be caused by media to the valve’s design. It allows the lining to fulfill its primary objective of extending the valve’s usable life. In the construction of the body of lined ball valves, our manufacturers use metal and high-quality lining. The lining might be made out of any one of a number of different materials, but the one we choose is the one that is most resistant to being broken down by the process media that will be taken into account.


  • GMK-lined Ball valves are high recovery valves because of their large opening size, which allows for a minimal pressure drop and a high flow capacity. 
  • These ball valves are the most low-maintenance of all valve types because of their straightforward design.

  • This valve can be quickly disassembled, and any broken or worn components can be easily replaced.
  • GMKBall valves are among the most durable options because of their resistance to damage from high pressures. 
  • They can be used in several settings across numerous sectors.
