This paper describes the operating and basic characteristics of a general purpose compressible flow bench facility developed to accomplish experimental test in fluid dynamics, as well as the required adaptations according to ISO 6358 for pneumatic fluid power components characterization such as, valves, regulators, filters, filter-regulators, cylinders, ... etc, are described. The experimental characterization of pneumatic fluid power components, espccially proportional valves and servo-valves are required when their performance must be modelled. The technical characteristics from suppliers are, in general, insufficient. The sonic conductance, critica! pressure ratio, coefficient of compressibility effect, and effective area, must be specified according to ISO 6358. In additíon, the corrected mass flow rate as function of the absolute inlet pressure and pressure ratio must be calculated. In this work, the experimental flow-rate characteristics of a Festo MPYE-5-3/8-010-B pnewnatic fluid ...
