Dongfeng KL truck parts Hand controlled valve bracket assembly 5102070-C3100

Built as a critical load-bearing component for the hand-controlled valve, this bracket assembly features a robust structural design to maintain valve stability during operation. The main body is crafted from 4mm-thick cold-rolled steel (Q235 grade) with integrated reinforcing ribs (8mm height, spaced 30mm apart), enhancing structural rigidity by 60% and reducing deflection to ≤0.5mm even under maximum valve operating force (500N). A precision-machined mounting platform (flatness ≤0.2mm) ensures the hand valve sits tightly without wobble, preventing air leakage caused by valve misalignment. The bracket’s U-shaped design wraps around the valve’s base, distributing stress evenly across the cab floor and avoiding localized deformation—critical for maintaining the brake system’s air pressure integrity

Engineered to withstand the harsh conditions of the truck’s cab floor—exposed to moisture, dust, and occasional chemical spills—the 5102070-C3100 bracket adopts a multi-layer anti-corrosion coating system. The surface undergoes zinc phosphating (12μm thickness) for rust priming, followed by cathodic electrophoresis (35μm thickness) that forms a seamless barrier against corrosion. The top layer is a matte black powder coating (40μm thickness) with excellent adhesion and scratch resistance (pencil hardness ≥H). This coating system passes 2000-hour neutral salt spray testing (ASTM B117) with no rust or peeling, adapting to humid coastal regions and snowy areas where road salt causes accelerated corrosion. Unlike uncoated steel brackets, it requires no additional maintenance to resist rust

Optimized to reduce vibration transfer and operational noise, the bracket assembly integrates dedicated dampening components. Rubber gaskets (EPDM material, 3mm thickness) are placed between the bracket and cab floor, isolating vibration from the truck’s chassis (10-500Hz) by 70% and preventing it from reaching the hand valve—avoiding false valve actuation caused by vibration. A foam buffer (10mm thickness) lines the bracket’s contact surface with the valve, reducing noise during valve operation to ≤40dB (quieter than standard office noise). The bolt holes feature self-locking nuts that prevent loosening over time, eliminating rattling caused by bracket movement. These features not only enhance driver comfort but also extend the hand valve’s service life by reducing vibration-induced wear

This hand-controlled valve bracket assembly is designed for efficient installation and long-term cost savings for Dongfeng KL operators. The pre-assembled structure (bracket + gaskets + hardware) allows a single technician to complete replacement in 30 minutes using only a socket wrench—no welding or drilling required. The OE-compatible design ensures perfect alignment with the hand valve and cab floor, avoiding the misfit issues of aftermarket brackets that cause brake system malfunctions (repair costs up to $800). The high-strength steel and corrosion-resistant coating extend the bracket’s service life to ≥500,000km—twice that of non-OE alternatives—reducing replacement frequency. By maintaining valve stability, it ensures reliable brake control, reducing the risk of accidents (average fleet accident cost $15,000+). Backed by a 2-year/250,000km Dongfeng warranty, it provides predictable maintenance expenses and enhances brake system reliability
