Low Temperature Cryogenic Valves

Keeping Cool Under Pressure: Cryogenic Valves for Low Temperature Environments

Choosing valves for cryogenic service can be complicated. The production, transport and storage of liquefied gases such as oxygen, nitrogen and natural gas demand a thoughtful solution.

Ladish’s cryogenic valves are produced to the rigid ‘Controlled Quality’ standards that assure dependable operating performance at sub-zero temperatures. The production, transport and storage of liquefied gases such as oxygen, nitrogen, natural gas (down to –425°F) demand a thoughtful solution. Our custom integral designed bonnets and modified extended bonnets provide safe, dependable service to LNG receiving terminals and liquification facilities as well as processes using liquid nitrogen and hydrogen. The main structural feature of these valves is the enclosed vapor chamber which isolates the packing from the cryogenic fluid allowing the packing to function properly. Ladish Valves ability to manufacture specifically designed cryogenic valves and to convert standard valves to cryogenic service, all in-house, allows for a completely controlled quality process. In addition, custom modification requests and any associated non-destructive testing can be expedited.

Valves for cryogenic service can be assembled in a clean room and be lubricant free or utilize lubricants compatible for cold service. The valves should be free from machine oil, grease, dirt or any foreign material. Any of these can inhibit the valve’s performance. Ladish’s clean room offers this complete solution in house.
