I . Operating Principle
CCW
Air to Port A forces the pistons outwards,causing the pinion to turn counter clockwise while the air is being exhausted from Port B.
CW
Air to Port B forces the pistons inwards,causing the pinion to turn clockwise while the air is being exhausted from Port A
II. Model andspecification
III Sizing:Doubleacting Actuators
The suggested safety for double acting actuators under normal working conditions is20%-30%
Example:
The torque needed by valve=100N.m
Air Supply=5Bar
According to the above table,we can choose the minimum model is F1-105DA
