A mothballed unit is kept in a state where it could restart. That means valves are preserved, spares are retained and stores are held, often for years, against a restart that keeps moving further away.
When the decision is finally made to release the material, the valve inventory is usually well preserved and well documented, because mothballing procedures require it. That makes it one of the better categories to sell.
The practical sequence
What happens, in order
What we need
The short version
A rough list, a location and a date. That is enough to start. If there are photographs, the review is faster and the number is more confident.
We do not need the valves cleaned, sorted or labelled. We do not need a data sheet for each item. And we do not need you to decide which items are worth selling before you send the list — that is the review.
Mixed lots and partial assemblies are included. If the material is awkward, unidentified or incomplete, say so and include it. A lot that describes its own problems is faster to price than one that does not.
Questions sellers ask
Do you buy preserved valves?
Yes, and preservation records help.
Can we keep part of the inventory?
Yes. We will price what is released and leave the rest.
What about valves still installed on the unit?
We buy removed equipment. Installed valves become relevant when the unit is decommissioned.
