pneumatic actuator - double acting
The operating principle of double acting actuator
Sizing example of HAITIMA double acting actuator:
Valve torque 100Nm plus 30% safety factor= 130N.m. Minimum
operating pressure 6bar. By reading down the 6bar column the
figure below 130N.m is 189.4N.m, The model number shown in
the left hand column is therefore HTD-105.
CCW-counter-clockwise
ccw-counter-clockwise

Air to port A forces the pistons outwards, causing the
piston to turn counter-clockwise while air is being
exhausted from port B.
CW-clockwise
cw-clockwise

Air to port B forces the pistons inwards, causing the
piston to turn clockwise while air is being exhausted
from port A.
