AT 350 180°) would be evaluated on request Different Actuator strokes other than 120° and 180° (e.g. 135 Stoke) are available on request. Cautions: obviously on the field applications when one or more of the above parameter are different, the moving time will be different. (A) The above indicated moving time of the actuator, are obtained in the following test conditions: (1) Room Temperature, (2) Actuator Stoke 120° and 180°,...

15 ® 3 POSITION ACTUATOR SIZING INFORMATION AIR TORQUE 3 position pneumatic actuator provide an operation of 0°- 45°- 90° or 0°-90°-180°. The intermediate position is achieved by a mechanical stop of movement on the 2 auxiliary pistons. This intermediate stop positions adjustable e.g. 90° actuators can provide 20° 30° 50° 75° etc. In order to control the operation of AT 3 position pneumatic actuators a system of solenoid valves controlling a sequence of air supplies to the actuator is required as described below: BALL VALVE Ball valve concept of construction is based essentially on a polished...

® 16 SIZING: DOUBLE ACTING ACTUATOR With rack and pinion construction the output torque of an actuator is obtained by multiplying the piston force (given by air supply pressure) by the pitch shaft radius (lever arm) as shown in fig. 1 less the force lost for friction (efficiency). Because of this concept, the output torque is linear as shown in the diagram A in both clockwise and counterclockwise rotation. The suggested safety factor for double acting actuators in normal working conditions is 15-20%. Sizing example of Double Acting AT actuator (see also technical data): • Published butterfly...
