Review factors
Condition, documents, and value context
Condition
Evaluation depends on the integrity of the diaphragm or piston seals and the absence of internal corrosion. Units with intact positioner linkages and verified fail-safe mechanisms typically retain better market viability.
Documentation
Providing recent calibration records, maintenance logs, and original factory specification sheets greatly assists in verifying the operational readiness of the actuators.
Evaluation context
General evaluation considerations include the actuator type, compatible valve size, current market demand for the specific brand, and the completeness of attached positioners or I/P transducers.
