PNEUMATIC ACTUATORS
PNEUMATIC ACTUATORS
WORKING CONDITIONS
Working Condition
Temperature: from 0º to + 80ºC; from - 20ºC to +80ºC with dry air
only. (from -40ºC to +150ºC in special execution)
Air supply: Minimum 40 psi; Maximum 130 psi
Operating media: Compressed filtered air, not necessarily lubricated.
In case of lubricated air, either non detergent oil or NBR
compatible oil, must be used.
Double Acting Operation
*CCW
Air is supplied to Port A forcing the pistons away from
each other (towards ends), rotating the drive pinion
counter-clockwise and exhausting air out of Port B
*CW
Air is supplied to Port B forcing the pistons toward
each other (towards center), rotating the drive pinion
clockwise and exhausting air out of Port A
Spring Return Operation * CCW
Air is supplied to Port A forcing the pisto
*CCW away from each (toward ends), rotating
Air is supplieddrive pinion
to Port counterclockwise
A forcing the pistons away and
from each other (towards ends),
exhausting rotating
air out the drive
of Port B
pinion counter-clockwise, compressing the springs
and exhausting air out of Port B
* CW
Air is supplied to Port B forcing the pis-
tons toward each other (toward center).
*FAIL CW
rotating drive pinion clockwise and
Air failure (loss of pressure) allows the compressed
springs to forceexhausting
the pistons air outeach
toward of Port
other
(towards center), rotating the drive pinion clockwise
and exhausting air out of Port A
