LNG duty at −162 °C sits below this tool's −46 °C floor, and the reason is data, not doubt about capability. Cryogenic valve selection is its own discipline — extended bonnets sized by rule, cold-box layout, drip plates, and a dedicated low-temperature type-test regime (the successor to BS 6364). None of that layer is in our knowledge base, so the tool refuses rather than approximates.
The capability itself is proven — including by Chinese makers, whose delivered cryogenic valves this site has reported. The boundary is that the published selection data does not exist in a form we can put in a table. Duties like this go to our engineering-review channel, and we confirm them by hand.
Typical duties
| LNG carrier and terminal isolation | ≈ −162 °C · cryogenic design · outside the automatic envelope |
|---|---|
| Cold-box and liquefaction-train valving | Cold-box layout and drip plates are design questions, not catalogue rows |
| High-pressure cryogenic control | Reported in the field at −130 °C / Class 2500 — see the award below |
This application sits outside the tool's data boundary — the reason is stated above, not hidden. Send the duty through the inquiry channel and a manufacturer's engineering team confirms it by hand.

What to watch
- This page deliberately runs no demo: every honest answer here is an engineered one.
- The old British cryogenic standard was withdrawn in 2015 — the linked article covers what a specification should name instead.
- China's own low-temperature valve test standard (GB/T 24925) is covered in a companion piece.
Where this connects on this site
- BS 6364: Withdrawn in 2015 — What a Cryogenic Valve Specification Should Name Instead
- GB/T 24925: China's Low-Temperature Valve Test Standard
- Reported: an NPS 36, Class 900, −196 °C cryogenic ball valve
- Reported: domestic cryogenic valves for LNG carriers
- Reported: a −130 °C, Class 2500 control-valve package for a CNOOC affiliate
Boundary rule: this page states single-point conclusions from the site's knowledge base — no supplier names, no matrices. The full 40-medium library lives in the selector.
