The Camflex is an eccentric rotating plug valve: the plug rotates out of the seat before it turns, so there is minimal seat wear and the valve handles dirty service better than a cage-guided globe body. The Camflex II refined the design with a clamped-in seat ring and a more compact actuator interface. Both generations remain in service in large numbers.
Because the design is compact and the body is a single casting, a used Camflex is a good rebuild candidate. The plug, seat ring and packing are all replaceable, and the actuator mounting is standard, which means a body with a damaged actuator is still useful to somebody.

Inspection points
What decides the price
Body and plug
Check the plug for erosion at the seat line and the body bore for wash. A worn plug is normal; a washed body is not.
Seat ring
The clamped seat ring is replaceable but must be present, because a missing ring means a missing part that is hard to source.
Actuator interface
Standard yoke and stem dimensions make these easy to re-actuate. Note the actuator model and the air failure direction.
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 Camflex valves without positioners?
Yes. The body and actuator are the bulk of the value, and positioners are frequently removed before storage.
Are older Camflex I valves of interest?
Yes, particularly in stainless and alloy bodies where the casting is sound.
