Table 2. Operating Media
Actuator Type Operating Media
Double-Acting and Single-Acting
Air, dry or lubricated and inert gases
Dew point at least 10K below ambient temperature
For sub-zero applications, take appropriate measures
Mentioned pressure levels are "gauge pressures".
Gauge pressure is equal to absolute pressure minus
atmospheric pressure.
1. Recommended air quality according ISO 8573-1 for normal operation: 7-5-4.
NOTE:
Use of lters, pressure regulators, lubricator and an oil/water separator mounted in the air
supply line, will allow a smooth and durable operation of the actuator.
For lubricated supply air, it is recommended to use a non-detergent oil without aggressive
additives, VG32, group 2 (ISO 3448).
