What Are Low Temperature & Cryogenic Ball Valves?

Cryogenic valves are specialized mechanical devices designed to control the flow of fluids at extremely low temperatures, typically below -196°C (-320.8°F). These valves are crucial components in various industries that handle liquefied gases such as Liquefied Natural Gas (LNG), Liquid Nitrogen (LIN), Liquid Oxygen (LOX), and Liquid Helium.

Indra cryogenic valves are available in all design configurations, Floating and Trunnion types. The side entry is one piece integral and split body.

Common applications include: LNG terminals and storage facilities, air separation plants handling LIN and LOX, and any process requiring reliable fluid control at temperatures below -196°C.

✓ Engineered for service down to -196°C — available in Floating and Trunnion, integral and split body

Applications

Ball Valves are the ideal choice for:

LNG terminals and storage — isolation valves for liquefied natural gas service, certified to EN ISO 28921-1 and EN ISO 28921-2

Air separation plants — control and isolation of Liquid Nitrogen (LIN) and Liquid Oxygen (LOX) at temperatures down to -196°C

Liquid Helium servic — extreme low-temperature applications requiring purpose-designed cryogenic valves

Any process requiring reliable fluid control at cryogenic temperatures where standard valves would fail due to material embrittlement or sealing degradation
