Ammonia and urea plants run at high pressure with aggressive chemistry, so their valves are alloy, high-class and often custom-trimmed for letdown duty. When a plant debottlenecks or replaces a synthesis loop, the removed set is usually complete and usually documented.
Fertiliser plants also hold deep spare inventories, because a shutdown for a missing valve is expensive. Those spares become surplus when the equipment they were bought for is replaced.

Selling into this sector
What to expect
Equipment from this sector usually arrives with a mix of documentation: some items tagged and recorded, some with nothing at all. Send what exists. A partial record is worth more than a claim that records exist.
Mixed lots are normal. We do not ask you to separate the documented items from the rest before sending a list.
Questions sellers ask
Do you buy high-pressure ammonia valves?
Yes, particularly Class 1500 and 2500 angle and globe valves.
Are urea service valves different?
They are usually stainless or special alloy because of carbamate corrosion. Mark the material clearly.
What about fertiliser plant spare holdings?
Those are exactly the crib lots we buy. Send the list with sizes and classes.
