Consider steady-state air consumption when specifying pneumatic positioners
Warminster, Standard cylinder PA -- All process and power industries use air compressors; the number and size of these compressors vary depending on the Pneumatic fitting air demand of each plant area. Textile cylinder Air compressors are costly to run and maintain, so any reduction of air usage will result in large financial savings in both the running cost of the compressors and maintenance reductions.
Most plants use pneumatically operated control valves and actuators that require positioners for modulating actuation of these final control elements. Pneumatic positioners constantly use air to position the final control element. This takes place during the up or down travel of the linear control actuator, or during the clockwise and counter clockwise travel of rotary actuators.
