• WEKA Cryogenic Valves ① Cryogenic bellows valves have vacuum-welded flanges and can be installed in vacuum-insulated cold boxes. They typically have a cryogenic length of 875mm and are designed in angle or right-angle configurations. Positioners and pneumatic or manual actuators operate the valves to close or regulate fluid. Thanks to the metal bellows, this valve achieves a high degree of sealing against the environment and ensures high reliability. ② Various options are available upon request, such as thermal connection with an 80K shield, limit switches for position feedback, use in special radiant or magnetic environments, connection dimensions, or thermal injection optimization. ③ Each WEKA valve undergoes a 1.5*PN pressure test and a comprehensive helium leak test. Sealing under the seat can also be checked at the nominal pressure or customer-defined operating pressure.
• WEKA Valves ① WEKA's valve technology is closely linked to cryogenic technology. Over the past 35 years, WEKA has established itself in the helium valve and customer-specific accessory market. ② When this material was not yet widespread, WEKA manufactured its first batch of stainless steel accessories in the 1950s. At that time, these applications were primarily found in the Swiss chemical, pharmaceutical, and nuclear industries. ③ The market is increasingly shifting towards liquid gases and cryogenics. Today, WEKA offers cryogenic valves from -270°C to approximately -200°C (in a low-pressure range up to 40 bar) and valves for room temperature applications, suitable for gases requiring high sealing performance within a pressure range of 1000 bar. Additionally, the program includes needle valves with a large nominal size of DN15 for both room and cryogenic applications, also suitable for demanding oxygen applications.
