Video Description:
In this video, we walk through the critical role of the main control valve cover housing in excavator hydraulic systems. You'll see how this distribution valve cover assembly functions within the EX-5, EX70, EX120, and EX330-3G models, with clear explanations of pilot control principles and proportional speed regulation. We demonstrate its integration with joystick operations and show how proper housing ensures reliable control of boom, stick, bucket, and swing functions.
