- Key functions & working principle
| Working Principle |
1. Hydraulic oil at system pressure enters the valve’s inlet port and is blocked by the spool in the neutral position |
| 2. Actuation (manual lever, solenoid, or pilot pressure) moves the spool to open flow paths to outlet ports connected to actuators (cylinders/motors) |
| 3. The spool’s position controls the volume and direction of oil flow: partial spool movement = reduced flow (slow actuator speed); full movement = maximum flow (full speed) |
| 4. When actuation stops, the spring-centered spool returns to neutral, closing flow paths and holding the actuator in position |
| 5. The integrated relief valve opens if pressure exceeds the rated limit, diverting oil back to the tank to prevent component damage |
| Core Functions |
1. Flow & Pressure Regulation: Controls the volume and pressure of hydraulic oil to actuators, enabling precise speed and force adjustment (e.g., slow/fast boom movement, light/heavy lifting) |
| 2. Direction Control: Redirects oil flow to move actuators forward/backward (e.g., extend/retract excavator arm, lift/lower loader bucket) |
| 3. Overpressure Protection: Built-in relief valve prevents hydraulic system damage from pressure spikes (e.g., sudden load impacts) |
| 4. Position Holding: Spring-centered spool locks actuators in place when not in use, preventing unintended movement (critical for operator safety) |
| 5. System Efficiency: Minimal internal leakage reduces energy loss, lowering fuel consumption and heat generation |
