A high$-$low circuit is shown below. It uses two pumps to allow for situations where at certain times in the work cycle you need fast actuator movernent le$.$g$.$ during extend and retract$)$ and at other limes the piston and rod are not moving $($c$.$e$.$ to clamp a workpiece for a certn$-$ in time interval$).$ Explain how this circuit can be used to accomplish this. Also loentify and explain the type of center position of the $4/3$DCI valve, and how it is used hore Use a separate circuit diegram for ench of the DCvalve positions that you discuss, stiowing the differentiflow peths and directions? make sure you provide separate circuits for each DC valve positions..
