Product Overview
The VT11023-16A is a high-performance analog proportional valve amplifier module from REXROTH, designed for closed-loop control of hydraulic proportional directional valves with position feedback. The module integrates an oscillator, demodulator, and adjustable ramp generator to convert analog command signals into precise solenoid control output, realizing accurate spool position regulation for hydraulic valves. It resolves hydraulic system control defects including unstable valve action, slow response speed, and inconsistent flow regulation, effectively improving the precision and stability of hydraulic transmission systems. Suitable for automation engineers and hydraulic system maintenance teams, it is widely used in industrial machine tool hydraulic systems, engineering machinery hydraulic units, and automated production line hydraulic control loops.
