LNG and cryogenic valves control liquefied natural gas and other
\nlow-temperature media in storage, transfer, vaporization and loading
\nsystems. WDL Valve supplies extended-bonnet ball, gate, globe and
\ncheck valves designed for temperatures down to -196\u00b0C.<\/p>\n<\/header>\n

What Are LNG and Cryogenic Valves?<\/h2>\n

LNG and cryogenic valves<\/a> are designed to isolate, regulate or
\nprevent reverse flow in piping systems carrying extremely cold
\nliquids and gases. LNG is normally stored at approximately
\n-162\u00b0C, while liquid nitrogen and some other cryogenic media may
\nrequire valve designs suitable for temperatures down to -196\u00b0C.<\/p>\n

At these temperatures, materials contract and some materials lose
\ntoughness. Seats, seals and packing can also change dimensions.
\nCryogenic valves therefore require suitable materials, extended
\nbonnets, controlled assembly and low-temperature testing.<\/p>\n<\/section>\n

\n

Where Are Cryogenic Valves Used?<\/h2>\n

Cryogenic valves are installed throughout LNG production, storage,
\ntransportation and distribution systems. Common installation
\nlocations include:<\/p>\n
