This type of valve primarily controls oil pressure in hydraulic systems to meet the requirements of actuators regarding output force, output torque, and various motion states. Based on the principle of force equilibrium acting on the valve spool, it adjusts the orifice opening to alter hydraulic resistance, thereby achieving functions such as pressure stabilization, pressure retention, pressure reduction, and pressure regulation, or utilizing pressure changes to sequence actuator operations.
