01
Use a positive-displacement hydraulic pump and atmospheric reservoir for oil supply.
02
Split the pump discharge through isolation and check valves to independent arm and outrigger directional control valves.
03
Add pressure transmitters and shared controllers on each branch to provide closed-loop pressure control.
Reuse for any hydraulic circuit where multiple actuators share a common pump and require independent directional control and pressure monitoring.
