A pressure control valve regulates the oil pressure within a hydraulic system to meet varying requirements of actuators regarding output force, output torque, and motion status. It operates based on the principle of balancing hydraulic force against spring force, thereby achieving and enhancing system performance such as pressure stabilization, pressure retention, pressure reduction, and pressure adjustment.
