The operating principle of double acting actuatorCCW-counter-clockwise CW-clockwise
Sizing example of NUTORK double acting actuator:Valve torque 100Nm plus 20% safety factor= 120Nm. Minimumoperating pressure 6bar(87psig). By reading down the 6bar(87psig) column the figure below 120Nm is 135.0Nm, The model number shown in the left hand column is therefore NKD-092.
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.

Sizing example of NUTORK spring return actuator:
Spring to close when air fails(air to open):
Valve torque 60Nm plus 20% safety factor = 72Nm. Minimum
operating pressure: 6bar(87psig). The spring return NUTORK actuator
selected is NKS-105-12.The NKS-105-12 has the following output
torques:
1.air torque 0°(valve close) = 122.5Nm > 72Nm
2.air torque 90°(valve open) = 80.6Nm
゜3.spring torque 90 (valve open) = 118.1Nm
4.spring torque 0°(valve close) = 75.9Nm > 72Nm
Air to port A forces the pistons outwards, causing the springs
to compress. The pinion turns counter-clockwise while air is
being exhausted through port B.
Loss of air pressure through port A allows the stored energy in the
springs to force the pistons inwards. The pinion turns clockwise
while air is being exhausted through port A.
