A cryogenic valve is built to operate at temperatures down to minus 196 degrees Celsius, with an extended bonnet to keep the packing warm, materials that stay tough when cold, and a design that keeps the seat tight through thermal cycling.
LNG liquefaction and export, air separation, industrial gas distribution and cryogenic storage all depend on them. Louisiana's LNG build-out has produced a steady flow of project surplus: valves bought for a phase that was re-scoped, commissioning spares, and replaced units from early trains.
We buy cryogenic valves in any quantity — single items, mixed pallets or whole cribs, including valves that need repair and assemblies that are missing parts. We do not require a clean inventory before reviewing a list.
| Common patterns | Extended bonnet globe and gate, Vacuum jacketed and cold box designs, Cryogenic ball and butterfly, Stainless and aluminium alloy bodies |
|---|---|
| Typical service | LNG liquefaction and export, Air separation, Industrial gases |
| What we look at | Temperature rating, body and trim material, bonnet type, size and class, plus impact test certification. We ask how the valve was stored, because that answers most condition questions. |
| What to keep | Keep them dry, capped and upright. Moisture ingress into an extended bonnet is the main killer of stored cryogenic valves. Keep the certification: impact test and material traceability are what a buyer asks for. |
Patterns and variants
What turns up most often
Variants matter because they change the buyer pool. A standard pattern sells to a rebuilder or a plant with the same service; a specialised trim sells to a much smaller group but often at a higher price. If you are unsure which variant you have, the nameplate or the trim marking will usually say.

How to protect the value
Keep them dry, capped and upright. Moisture ingress into an extended bonnet is the main killer of stored cryogenic valves. Keep the certification: impact test and material traceability are what a buyer asks for.
Where they come from
Industries and services
- LNG liquefaction and export
- Air separation
- Industrial gases
Most of the surplus we see comes from plants that have replaced equipment for a reason that has nothing to do with the valve: a unit was re-rated, a line was re-piped, a control loop was upgraded or a project was re-scoped. The valve is simply the part that has to move.

Read →Questions sellers ask
Do you buy valves without impact test certificates?
Yes, but the price reflects it. Cryogenic buyers expect material traceability, so documentation is a large part of the value.
How should stored cryogenic valves be kept?
Dry, capped, upright and away from standing water. If they have been outside in the rain for years, tell us.
Are LNG project leftovers of interest?
Yes. Commissioning spares and re-scoped project material are exactly the kind of stock we look for.
