Vickers-KBDG4V 5 2C50N Z M2 PC7HAVANT

Designed for applications needing precise flow management, this proportional directional control valve allows smooth, stepless control of actuator speed and direction, which would definitely fit the bill for a log splitter.

The Z designation on this valve means the electronics are integrated directly into the unit rather than being housed separately. For wiring purposes, that means the proportional control circuitry is already built in, so you're not dealing with a remote amplifier box on its own. The PC7 portion of the model code points to the specific amplifier card configuration tied to this series, so the command signal input and internal electronics are matched to that setup from the factory.
