Dual Circuit Filling Valve 803007014 for XCMG Wheel Loader – OEM Replacement Brake Charging Valve

Product Specifications – Dual Circuit Filling Valve 803007014

Product Overview

The Dual Circuit Filling Valve 803007014 is a critical hydraulic brake component designed for XCMG wheel loaders. This valve regulates the charging process of the dual brake circuit, ensuring stable pressure delivery to both brake lines for safe and reliable machine stopping performance. It is manufactured to meet or exceed original equipment specifications.

Key Specifications

• Part Number: 803007014

• Product Type: Dual Circuit Filling Valve / Brake Charging Valve

• Compatibility: XCMG Wheel Loaders (confirm model before ordering)

• Material: High-strength cast iron body with precision-machined internal components

• Operating Pressure: Matches OEM specification for XCMG brake systems

• Connection Type: Standard threaded ports for direct replacement

• Sealing: Nitrile rubber seals resistant to hydraulic fluid and temperature variation

Functional Description

The dual circuit filling valve serves two primary functions in the XCMG wheel loader brake system. First, it maintains equal pressure between the two independent brake circuits during normal operation. Second, if one circuit loses pressure due to a leak or failure, the valve isolates the damaged circuit so the remaining circuit continues to provide braking force. This dual-circuit design is a fundamental safety feature in heavy equipment braking systems.

Installation Notes

• Verify the part number 803007014 matches your existing valve before installation.

• Inspect all hydraulic lines and fittings for wear or contamination.

• Bleed the brake system thoroughly after replacement to remove air pockets.

• Use only approved hydraulic fluid as specified in your XCMG wheel loader service manual.

• Torque all connections to the manufacturer's recommended specification.

Maintenance Tips

• Check for external leaks around the valve body and fittings every 500 operating hours.

• Replace seals if any weeping or pressure loss is detected.

• Keep the hydraulic fluid clean to prevent internal valve sticking.

• Store spare valves in a dry, dust-free environment.
