Proportional solenoid valve receives 4-20mA or 0-10V analog command signal from controller. The electromagnetic coil drives spool displacement proportionally, adjusting valve opening area to realize stepless regulation of fluid flow and pressure. Built-in LVDT position feedback forms closed-loop correction, improving regulation accuracy and anti-disturbance performance.
