Cryogenic Ball Valve

LibertyCES has documented Cryogenic Ball Valve specified across 2 sector applications, including LNG / Liquefied Natural Gas and Air Separation.

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. — examples include AVCO 1500 Series (3-piece full port fire safe cryogenic, 1/4"-4", up to Class 600 / 2000 WOG; single-piece cryogenic bonnet extension bolted to the body, sealed twice via Flexitallic spiral wound gasket; Hastelloy C and Monel 400 body/ball/stem; named markets aerospace, petrochemical, LNG, liquid oxygen), AVCO 9500 Series (2-piece flanged cryogenic, 1-1/2"-6", Class 150/300; named markets power, oil & gas, chemical, LNG, liquid oxygen; customizable bonnet lengths incl. subterranean box installs). This is well-documented in LibertyCES's field data.

The double-seal detail is the real engineering content: the 1500 Series seals twice — at the top of the valve AND the top of the bonnet — which is what makes a cryogenic extension trustworthy rather than just longer. The L-port diverter and Vee-ported control configurations mean one cryogenic body covers isolation, diversion and throttling. 9500's customizable bonnet lengths including subterranean box installations is the install-side flexibility to lead with on an LNG terminal page. Materials to confirm: Hastelloy C and Monel 400 body/ball/stem options (1500 Series), 316SS, Carbon steel, Flexitallic spiral wound gasket, Delrin / PEEK seats (HP1100 platform, for reference). Specific chemicals include LNG / liquefied natural gas, natural gas, propane, butylene, liquid oxygen (co-listed service).
