Jamesbury built its reputation on soft-seated ball valves and the Wafer-Sphere butterfly valve, with a strong installed base in pulp and paper, chemical and process service. The valves are designed for tight shutoff and are commonly actuated.
Surplus comes from mills and process plants during upgrades and rebuilds, often as actuated assemblies with linkage and limit switches intact.

Seller guides
Jamesbury equipment, in detail
What we look at
Reviewing Jamesbury equipment
Seat and ball
Scoring is normal; cracking or a damaged ball is more serious.
Actuator linkage
Bracket, coupling and limit switches. Complete packages are worth more.
Body material
Stainless bodies are common in mill service and hold value well.
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 Jamesbury equipment?
Yes. We buy Jamesbury 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 Jamesbury 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.
