580M2 REAR CONTROL VALVE SPOOL – STABILIZER
This Rear Stabilizer Control Valve Spool is a key hydraulic component used to regulate oil flow to the stabilizer legs on the rear section of CASE 580 series backhoe loaders. It controls stabilizer UP and DOWN movements, ensuring firm machine positioning, stronger ground stability, and safer excavation operations.
Made from precision-machined, hardened alloy steel, the spool offers superior wear resistance, excellent sealing, and reliable performance under high pressure. Replacing a worn or leaking spool restores proper stabilizer function, reduces internal leakage, and improves machine stability during digging, lifting, and loading tasks.
