The working principle of the hydraulic valve is based on two core mechanisms: pressure-spring balance and throttling control.
By adjusting the displacement of the valve spool, the oil flow path or resistance is altered. Directional valves control the flow direction, while pressure valves regulate the pressure level.
The flow valve stabilizes the speed, while servo valves and proportional valves enable precise conversion of electro-hydraulic signals.
