The operating principle of double acting actuatorCCW-counter-clockwise CW-clockwise

Sizing example of PASCO 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 PASCO 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 PASCO 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.
