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.
