The values from the correctiondiagram on page 7 have also been used for the curves for the differentpressure values. The graph also shows that is it very important toensure that the pressure supplied to the inlet port of the motor iscorrect, in order to allow the motor to work at maximum capacity. Ifthe valve supplying a large motor is too small, or if the supply line isunderspecified, the pressure at the inlet port may be so low that themotor is unable to do its work. One solution would be to upgrade thevalve and supply system, or alternatively you could replace the motorwith a smaller motor with lower air consumption. The result would beincreased pressure at the inlet port, which means that the smallermotor could carry out the necessary work. However, you may need toselect a smaller motor with a lower free speed in order to obtain sufficienttorque at the outgoing shaft.26Parker Hannifin CorporationPneumatic Division - Europe
