LOADER BUCKET CONTROL VALVE SPOOL

This Loader Bucket Control Valve Spool is a critical hydraulic component responsible for regulating oil flow to the loader bucket functions on Case backhoe loaders. Manufactured with high-precision machining and hardened materials, it provides excellent sealing, smooth operation, and long-term resistance against wear, pressure, and contamination.

Designed to meet OEM specifications, this spool ensures accurate hydraulic response for bucket lift, lower, curl, and dump operations. Replacing a worn or scratched spool restores the original hydraulic performance, eliminates internal leakage, and significantly improves machine efficiency and operator control.
