Jamesbury soft-seated ball valves use PTFE or reinforced PTFE seats to give bubble-tight shutoff in process isolation. They are common in pulp and paper stock lines, chemical service and utility isolation, and they are usually actuated in mill installations.
Because the seats are replaceable and the bodies are robust, a used valve with a scored ball is still a rebuild candidate. The actuator package, if present, is a significant part of the value.

Inspection points
What decides the price
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.
What to send
Making the review quick
A wide photograph of the whole unit, a close photograph of the valve nameplate, and the model number if you have it. If there are several identical units, one set of photographs and a quantity is enough.
If the equipment is already separated, keep the parts together and label them as a set. A matched pair is worth more than two orphans.
