Pressure Oil
The circuit relief setting of the pressure oil supply should be no less than 3000 psi (207 bar)
to maximum of 5000 psi (345 bar). Motor torque is directly proportional to the value of the
supplied pressure and so higher supplied pressure translates into increased performance
and reduced time required to bring the rotor from dead stop to full speed. The minimum
recommended pressure supply line size is ¾” (19mm) inside diameter and capable of
withstanding pressure established by the circuit relief setting.
Main Return Oil
Main return oil may pass back to tank through the directional control valve section from
which the pressure oil is supplied. A more efficient configuration is to have the return oil
circumvent the control valve directly back to tank thereby avoiding back pressure and heat
generated due to throttling losses encountered in the directional control valve.
