Pneumatic Actuator - Double Acting Sizing example of NUTORK 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 135.0Nm, The model number shown in the left hand column is therefore NKD-092. The operating principle of double acting actuator 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. Air to port B forces the pistons inwards, causing the piston to turn...

Pneumatic Actuator - Spring Return (Fail Safe) 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 The operating principle of single acting spring return actuator...
