804022161 Foot brake valve XCMG Excavator Parts
The XCMG 804022161 Foot Brake Valve is a precision-engineered hydraulic control component designed specifically for XCMG excavators and heavy machinery. As a critical safety component of the machine's braking system, this foot-operated pilot valve converts the operator's pedal input into proportional hydraulic pressure, delivering smooth, reliable stopping power in demanding construction and mining environments.
This valve is a key element in the excavator's hydraulic brake circuit, working in conjunction with brake accumulators, charging valves, and brake actuators to ensure consistent and progressive braking performance.
- Proportional Brake Control
The valve delivers output pressure directly proportional to pedal input, allowing operators to modulate braking force with precision. This ensures smooth deceleration regardless of load or ground conditions, reducing operator fatigue and component wear.
- Dual-Circuit Safety Design
Compatible with XCMG's dual-circuit hydraulic braking systems, the valve supports fail-safe operation. In the event of pressure loss in one circuit, the other remains functional, providing backup stopping power.
- Robust Construction for Heavy-Duty Applications
The valve body is precision-machined from high-strength materials with a corrosion-resistant finish. Internal components include hardened camshafts, precision-ground spools, and durable seals designed to withstand high system pressures up to [18 MPa] and operating temperatures ranging from -40°C to +120°C.
- Reliable Sealing & Protection
High-quality O-rings, gaskets, and bushings create tight seals to prevent hydraulic fluid leaks, maintaining system pressure and efficiency. Dust covers and end caps shield internal components from contamination, extending service life.
- Minimal Hysteresis & Stable Performance
The valve features a linear response curve with minimal hysteresis, ensuring consistent pedal feel and stable pressure hold when the pedal is held stationary.
