 Sizing example of HAITIMA double acting actuator:
Valve torque 100Nm plus 20% safety factor= 120Nm. Minimum
operating pressure 6bar(87psig). By reading down the 6bar(87
psig) column the figure below 120Nm is 136.4Nm, The model
number shown in the left hand column is therefore NKD-092. The operating principle of double acting actuator
 Air to port A forces the pistons outwards, causing the
piston to turn counter-clockwise while air is being
exhausted from port B. |
 Air to port B forces the pistons inwards, causing the
piston to turn clockwise while air is being exhausted
from port A. |
