580M2 REAR CONTROL VALVE SPOOL - BOOM

580M2 REAR CONTROL VALVE SPOOL – BOOM

This Rear Boom Control Valve Spool is a critical hydraulic component used in the backhoe (rear) section of CASE 580 series machines. It regulates the hydraulic oil flow to the boom cylinder, ensuring smooth lifting, lowering, and stable hydraulic response during excavation operations.

Manufactured with high-precision machining and hardened alloy steel, the spool provides excellent sealing performance, durability under high pressure, and long service life. Replacing a worn or scratched spool restores the original hydraulic power, reduces internal leakage, and significantly improves digging efficiency.

Key Features

• Precision-machined spool for accurate hydraulic control

• Hardened surface for superior wear resistance

• Low internal leakage for stable pressure flow

• Smooth boom raising & lowering action

• OEM-standard dimensions for perfect fitment

• Durable under high temperature & working pressure

Functions

• Controls hydraulic flow to the rear boom cylinder

• Regulates BOOM up & down operations

• Restores smooth hydraulic performance

• Improves digging power, speed, and operator control

• Reduces leakage, improves efficiency and safety
