Hydraulic control valve - principle and use of directional control valve
The directional control valve is used to control the direction of the liquid flow in the system to achieve the direction of movement of the control actuator (forward and reverse rotation of the hydraulic motor, forward and reverse operation of the hydraulic cylinder, etc.). Commonly used directional control valves are: check valves, manual reversing valves and electromagnetic reversing valves.

Basic knowledge of proportional valves
Proportional valves are a new type of hydraulic control device. Proportional solenoids are used to replace the original control parts on ordinary pressure valves, flow valves and directional valves, and the pressure, flow or direction of the oil flow is continuously and proportionally controlled remotely according to the input electrical signal.
