We have developed a long experience in manufacturing valves for low and cryogenic temperatures. A special selection of materials, seals, bonnet design, combined with expertise and careful machining of the sealing surfaces allow our trunnion mounted and floating ball valves to operate down to -196°C. The high quality of our cryogenic valves has been proven by several certifications and prototype testing carried out over the years. Our Assembly and Testing area is provided with all the latest generation technologies to carry out testing at cryogenic temperatures, including leak detection testing and torque testing. Vent and drain can also be provided with pad flanges c/w blind flanges to prevent leakages on threaded connections in sour service.
