Product Overview
The Rexroth VT-DFPE-A-22/G24K0/2A0F/V-021 (Material Number R901229920) is a high-performance proportional control valve designed for precise electro-hydraulic control of flow and pressure in demanding industrial systems. As part of the Rexroth proportional valve family, this unit features a pilot-operated, two-stage design with integrated digital amplifier electronics (OBE), enabling closed-loop position control of the main spool. The valve converts a proportional electrical input signal into a continuously variable hydraulic output, providing smooth, infinitely adjustable actuation of actuators, cylinders, and motors. Its robust construction and high-resolution spool positioning make it ideal for applications requiring fast response, excellent repeatability, and minimal hysteresis.
