Tips: Difference between angular stroke and linear stroke pneumatic actuators

When the angular stroke pneumatic actuator is working, its torque is in an arc map, which is consistent with the map when the ball valve and butterfly valve are opened and closed, so they can work more efficiently when matched.
The straight-stroke gear type is about the force of the engagement between the piston and the gear. Due to the rough precision control, the damage rate is large.
