YB60002551/YB60002553 Control valve is suitable for Hitachi ZX120-5A 130-5B 135-5A 130-7 High Quality Control Valve, Construction Machinery Aftermarke

The distribution valve YB60002551/YB60002553 is a key component in the excavator's hydraulic system. It controls hydraulic oil flow direction and pressure distribution to achieve various excavator movements. Its core functions include:

• Core component of the system - As a key component of the hydraulic system, it controls the flow direction and pressure distribution of hydraulic oil to realize various movements of the excavator.
• Integrated multi-valve functions - Integrates multiple valves such as main relief valve and overflow valve, precisely controls pressure and flow to ensure stable and accurate movements.
• Clear fault types - Prone to pressure abnormalities and valve stem wear; need to regularly calibrate pressure and replace worn parts.
• Specific maintenance requirements - Requires regular cleaning and seal inspection; professional operation, model matching, commissioning and testing are needed for repair and replacement.
