7.2 Natural gas as actuator medium
Introduction
Note when using an actuator with natural gas that this can escape at the following points:
● At the exhaust air outlet with sound absorber.
● At the enclosure vent.
● At the control air outlet near the pneumatic connections.
Note
Exhaust air outlet with a sound absorber
The positioner is supplied as standard with a sound absorber. To provide an outlet for the exhaust air, replace the sound
absorber by a G¼ pipe coupling.
Enclosure ventilation and control air outlet
Enclosure ventilation and control air outlet cannot be collected and channeled off.
Please refer to the following table for the maximum ventilation values.
Maximum values for escaping natural gas
Ventilation process
Ventilation of the enclosure volume. Purge air switch is at
"IN":
Ventilation via the control air outlet near the pneumatic
connections:
Ventilation through the exhaust air outlet with a sound
absorber
Volume
1) Depending on the actuating pressure and volume of the actuator as well as the frequency of control. The maximum flow
rate is 470 Nl/min at a differential pressure of 7 bar.
