Fisher control valve bodies divide into two broad families. The easy-e globe range, including the ED, ET, EZ and EWT patterns, uses a cage-guided or top-guided plug in a globe body and covers the majority of small to medium process control loops. The Vee-Ball rotary range, including the V150, V200 and V300, uses a segmented ball in a flanged or wafer body for higher capacity and slurry-tolerant service.
What separates a saleable valve from a parts donor is usually documentation and completeness. A body with its original tag, its actuator and its positioner can be matched to a data sheet and re-trimmed. A bare body with the yoke cut off and no tag is a casting with a story nobody can verify.

Inspection points
What decides the price
Body and trim
Size, class, body material, trim characteristic and whether the cage, plug and seat ring are present. Cavitation and noise trim is worth more than standard trim.
Actuator match
A body and actuator that were matched at the factory stay matched. Note the actuator size and the bench set if it is marked.
Tag and data sheet
The tag number is the most valuable piece of information on the valve. Photograph it before anything is disconnected.
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 Fisher valves with the actuator removed?
Yes, but the assembly is worth more intact. If the actuator has already been removed, keep it with the body and tell us which one belongs to which.
What about valves with damaged trim?
Cage, plug and seat are replaceable, so a worn trim does not eliminate value. A cracked body or a bent stem does.
