- Key functions & working principle
| Working Principle |
1. When the operator turns the steering wheel, mechanical force is transmitted to the valve’s spool via a linkage/rotary shaft, shifting the spool from its neutral position |
| 2. The shifted spool opens oil passages, directing pressurized hydraulic oil from the machine’s main hydraulic pump to one side of the steering cylinder (e.g., left cylinder for left turn) |
| 3. Oil is simultaneously routed from the opposite side of the steering cylinder back to the hydraulic tank (return line), allowing the cylinder to extend/retract |
| 4. The pressure-compensated design modulates oil flow rate to match steering wheel speed, ensuring smooth, proportional movement of the front axle/wheels |
| 5. When the steering wheel is centered, the spool returns to neutral, closing oil passages and locking the steering cylinder(s) in position to maintain straight travel |
| Core Functions |
1. Precise Steering Control: Converts operator input into accurate hydraulic oil flow, enabling smooth left/right turns and straight-line stability for wheel loaders/graders |
| 2. Load Compensation: Maintains consistent steering response regardless of engine speed or hydraulic system load (e.g., lifting heavy loads while steering) |
| 3. Overload Protection: Integrated relief valve prevents damage to steering cylinders/linkages from excessive pressure |
| 4. Safety: Emergency manual override (where fitted) ensures basic steering control if hydraulic power is lost |
| 5. Efficiency: Minimal internal leakage reduces hydraulic energy loss, lowering fuel consumption and heat generation |
