Main components: Leg control valve, multi-way directional valve, slewing balance valve, lifting balance valve, slewing buffer valve, selector valve, controller.

The slewing balance valve uses bypass leakage to improve the stiffness of the slewing system, effectively suppressing the shaking and impact caused by the long-arm load swinging.

The slewing buffer valve adopts gradual buffer overflow technology, effectively filtering the transient impact during slewing startup, making the slewing startup smoother. The delayed closing function of the slewing brake allows sufficient time for the release of kinetic energy during slewing shutdown, improving slewing stability.

The multi-way valve has a wide speed range, ensuring a more reasonable distribution of flow gain for various actions. The throttle speed control function improves the stiffness of each system, contributing to stable and reliable operation of each action.

The electronic control system has multiple ports and CAN bus transmission capability, allowing control of various electronic control multi-way valves, engines, torque limits, and other functions. It has a rich communication interface.
