The Samson 3241 and 3244 series are single-seated globe valves with a modular seat and plug arrangement, which makes re-trimming practical. They are typically supplied with a 3271 or 3277 pneumatic actuator and a 3730 series positioner, and they appear across chemical, pharmaceutical and utility installations where precise control at moderate pressure drop is needed.
Because the trim is modular and the body is a straightforward casting, a used Samson globe valve with an intact body and a complete actuator is a genuine rebuild candidate rather than a spare-parts box. The limiting factor is usually documentation: a body with no tag and no data sheet takes longer to place.

Inspection points
What decides the price
Trim and characteristic
Equal percentage and linear trims are both common. Note which one, and whether the plug is balanced or unbalanced.
Actuator and bench set
The diaphragm actuator and its spring range determine what the valve can do. Photograph the actuator plate.
Body material
Cast steel, stainless and alloy bodies all appear. Material marking on the body is the first thing to capture.
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.
Questions sellers ask
Do you buy Samson valves from pharmaceutical plants?
Yes. Clean-service stainless bodies are of particular interest when the documentation is intact.
Are Samson positioners bought separately?
Sometimes, in quantity. Send the model numbers.
