This high-response proportional valve adopts a direct-acting servo-grade spool, built-in LVDT displacement closed-loop and OBE integrated drive board. It boasts fast dynamic response, low hysteresis and outstanding repeat positioning accuracy, and operates smoothly at low speed without crawling or chattering. It combines the control performance of servo valves with the high durability and strong contamination resistance of proportional valves. Widely used in high-precision control scenarios such as servo presses, brick making machinery and metallurgical equipment, the product maintains consistently reliable performance.
