Product Overview
The Eaton Vickers KDG4V-3-2C20N-Z-M-U-H7-60 (02-146720) is a high-performance proportional directional valve from the Vickers KDG4V series, engineered for precise electro-hydraulic control of flow direction and magnitude in industrial hydraulic systems. This valve utilizes a proportional solenoid actuator acting on a precision-ground spool within a hardened valve body, enabling infinitely variable flow control proportional to the electrical input signal. The KDG4V-3 platform is a proven, globally recognized design used as a pilot or main-stage control element in demanding motion-control circuits, offering excellent repeatability, low hysteresis, and fast dynamic response. With a CETOP 3 (NG6) mounting interface and a 20 L/min nominal flow rating, this valve is ideally suited for integration into manifold-based systems requiring accurate velocity and position control of hydraulic actuators.
