A cryogenic gate valve is somewhat different mechanically as compared to a regular gate valve. There is an extension stem in a cryogenic gate valve ensuring the stem seal temperature remains higher than that of the medium. In addition, a possible pressure increase in the intermediate space is mechanically prevented. Typically, the pressure in the intermediate space of cryogenic gate valves is released through a bore in the gate or body, for which reason the valves are tight in one direction only. Cryogenic gate valves are clean and dry.
Our range of cryogenic gate valves is comprehensive. Smaller cryogenic gate valves are manufactured by OMB and larger size classes by RT.
