Mechanical Unloading Valve: Designed for KDJY LY LG SY Loader

Product Overview

The mechanical unloading valve is specifically designed for small loaders and 4×4 forklifts. As a critical component in hydraulic or pneumatic systems, it automatically unloads excess pressure when the system reaches a preset value, ensuring operational safety and extending equipment lifespan. Its mechanical control mechanism does not require a power source, making it suitable for heavy-duty and high-intensity applications.
