LNG is named explicitly on both AVCO cryogenic ball valve pages. Real systematic pattern for spares planning: AVCO pairs every standard series with a cryogenic-bonnet variant — 1100→1500, 9100→9500, 11100→11500, 19100→19500 — so the LNG valve is the same base platform with an extended bonnet.

AVCO's cryogenic bonnet is sealed twice — at the top of the valve AND the top of the bonnet — a real double-seal design specifically because a single-seal cryogenic bonnet is where LNG service valves typically leak as the bonnet thermal-cycles.
AVCO systematically pairs every standard ball valve platform with a cryogenic-bonnet variant — 1100→1500, 9100→9500 — so an LNG valve isn't a bespoke product, it's the same base platform with an extended, doubly-sealed bonnet, which matters for spares planning across a liquefaction train.

FAQ
Is Cryogenic Ball Valve used in LNG / Liquefied Natural Gas?
LNG is named explicitly on both AVCO cryogenic ball valve pages. Real systematic pattern for spares planning: AVCO pairs every standard series with a cryogenic-bonnet variant — 1100→1500, 9100→9500, 11100→11500, 19100→19500 — so the LNG valve is the same base platform with an extended bonnet. This is strong evidence.
What products are specified for Cryogenic Ball Valve in LNG / Liquefied Natural Gas?
