Bonjour

j'aimerai savoir c'est quoi la différence entre "BENCH SET" et "OPERATING RANGE" dans les actuateurs pneumatiques des vannes de contrôle.

je vous remercie

The difference between the terms “Air Operating Range” and “Bench Set.”

- Air Operating Range refers to the low and high range of air pressure used in controlling the actuator position, the air control signal. This is typically going to be an industry standard 3-15 PSI or 6-30 PSI, for instance.

- The “Bench Set” is the lower and upper air signal pressures used to set the factory preloading of the actuator spring.

They are not the same thing, although sometimes may have the same values; i.e., 3-15 PSI Air Operating Range/3-15 PSI Bench Set.
