Throttling is synonymous with air flow control and affects speed more than torque.
Pressure regulation affects torque more than speed
All performance graphs of Atlas Copco air motors are given for an inlet pressure of 6.3 bars. For other air pressures the performance curves must be recalculated.
To calculate performance data the motor data at 6.3 bar has to be multiplied by the correction factor shown in the table below.
Another way to find out how to pressure regulate or throttle motors is to use the Air Motors selection program.
