XCMG Spare Parts BALANCE VALVE 803439044

This 803439044 balance valve is a genuine XCMG spare part, designed for loader and excavator hydraulic systems. It directly replaces the original component without modification.

Machined from high-strength steel with a hard chrome finish, it resists wear and corrosion. Internal tolerances match factory specifications to prevent internal leakage and maintain stable pressure.

The valve automatically balances pressure between cylinder chambers, reducing shock and vibration during boom or arm movement. This protects hoses, seals, and the main control valve from pressure spikes.

Before installation, check that your machine’s hydraulic oil is clean. Contamination is the main cause of premature spool wear. Always replace O-rings and torque to 45–50 Nm as per XCMG manual.

Backed by XCMG quality assurance, this balance valve delivers reliable performance, reduces downtime, and ensures compliance with factory specifications for construction and mining equipment.
