Powell manufactures cast steel, stainless and alloy gate, globe and check valves, with particular strength in cryogenic, severe service and power generation applications. The company also builds specialised valves for nuclear and research service.
Surplus Powell equipment usually comes from LNG, power and refinery work where documentation exists and the valves were specified for difficult duty. Cryogenic patterns are the most sought after.

Seller guides
Powell equipment, in detail
What we look at
Reviewing Powell equipment
Impact testing
Charpy impact test certification is expected. If you have it, say so.
Bonnet condition
Look for water marks and corrosion inside the extended bonnet.
Seat and disc
Cryogenic seats are delicate. Photograph the seat area through the bore.
A detailed, accurate list is more useful than a generic brand mention. If you can tell us the model, the size, the class and what is attached, the review is straightforward. If you cannot, photographs of the nameplates will get us most of the way.
What to preserve
Before anything is disconnected
Keep the assembly together, keep the tag on the valve, and photograph the nameplates before anything is separated. Most of the value lost on branded equipment is lost in the ten minutes after removal, not in the years before it.
Questions sellers ask
Do you buy used Powell equipment?
Yes. We buy Powell equipment as surplus, in single lots or as part of a whole crib. We buy it as equipment, not as scrap, and we make no claim about its fitness for future service.
Is Powell surplus worth more than unbranded equipment?
Often yes, because the brand tells a buyer what the specification is and where parts come from. The premium depends on the model, the condition and the documentation.
What if the nameplate is missing?
Send photographs of the body and any cast markings. Brand and model can often be established from the shape and the marking, though the price reflects the uncertainty.
