KTM;Westlock Ball Valves, Floating, KTM Ball Valves for Low Temperature and Cryogenic Applications 

Floating Type (long bonnet) and Trunnion Type (short bonnet) Ball Valve Structures

KTM ball valves have been widely used in low temperature and cryogenic applications, including LNG (Liquefied Natural Gas) which is fast becoming a better alternative source of energy. With a proven design and after many successful references, the KTM brand name continues to be preferred by end-users as the process quality ball valve of choice.

Features & Benefits:

  • Extension bonnet protects the gland packing. Two types of extension bonnet (short and long) are available to better locate the “Gland Packing” at ambient temperature zone. This will help protect it from freeze-damage caused by low temperature fluid.
  • Cavity pressure relief.
  • Excellent seat and seal design minimizes leakage.
  • Low operating torque for smoother operations.
  • Fire-safe design.
  • Fugitive emission compliance.
  • Rigid body construction minimizes thermal shrinkage.
