Product Overview
The Danfoss KDG4V-5-33C50N-M-U-H7-30 (material number 02-157268) is a high-performance proportional directional control valve from the Danfoss KDG4V series, engineered for precise, infinitely variable control of hydraulic actuator direction, speed, and position. This four-way, three-position (4/3) valve utilizes a proportional solenoid on one or both ends acting against a spring-centered spool, delivering smooth, stepless flow metering proportional to the electrical command signal. With a CETOP 5 (NG10 / ISO 4401-05) subplate mounting interface, the KDG4V-5 series is a direct-fit, drop-in replacement for Vickers KDG4V-5 and compatible proportional valve platforms, making it ideal for closed-loop and open-loop industrial motion control systems requiring high dynamic response and repeatable metering accuracy.
