580 M LOADER LIFT CONTROL VALVE SPOOL

This Loader Lift Control Valve Spool is an essential hydraulic component responsible for regulating oil flow to the loader lift cylinders on Case 580 series backhoe loaders. It ensures precise control of the loader arm lifting and lowering functions, providing smooth, responsive, and stable hydraulic performance during heavy-duty operations.

Manufactured using high-precision machining and hardened steel, this spool delivers long-term durability, excellent sealing, and reduced internal leakage. Replacing a worn, scratched, or leaking spool restores the original lifting power, improves operator control, and increases overall work efficiency.
