Hydraulic System
1)Proportional Priority Pressure Compensating (PPPC) Valves contain specifically cut spools for motor grader applications, continuously matching of hydraulic flow and pressure to power demands, allowing ease of multi-function control for optimizing working efficiency
2)World-class variable displacement piston pump, efficiently reduces SEM922 motor grader power consumption and hydraulic system heat, improving fuel efficiency
3)Load-sensing hydraulic system provides SEM922 motor grader consistent and precise blade movement, improving finishing performance
4)Inboard lock check valves within PPPC, prevents inadvertent cylinder movement and potential leak
