Request a Spec Review →Yes. LibertyCES has documented Cryogenic Ball Valve in LNG / Liquefied Natural Gas applications, including AVCO 1500 Series and AVCO 9500 Series. The right model depends on the fluid, concentration, temperature, flow and duty cycle, so send James your process data for a free spec review before final selection.
Notes from the vendor documentation
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 9500 Series size & pressure | 1-1/2"-6", ANSI Class 150/300; customizable bonnet lengths including subterranean box installs | AVCO Valve — Ball Valve Families |
| Named markets | 1500 Series: aerospace, petrochemical, LNG, liquid oxygen; 9500 Series: power, oil & gas, chemical, LNG, liquid oxygen | AVCO Valve — Ball Valve Families |
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.
