Dongfeng GX truck parts Trailer valve bracket assembly 2701510-H11A2

Built as the critical load-bearing component for the trailer control valve, this bracket features a robust design to withstand dynamic and mechanical stresses. The main body is fabricated from Q550 high-strength steel via precision stamping, with an 8mm-thick base and 6mm-thick U-shaped reinforcing ribs—achieving a static load capacity of 300N, easily securing the trailer valve (weight ~5kg) and resisting vibration-induced displacement. The stamping process optimizes material grain flow, enhancing fatigue resistance to withstand 500,000km of road vibration without structural deformation. The multi-point mounting design distributes the valve’s weight evenly across the frame, limiting deflection to ≤0.8mm under maximum load and preventing air pipe leaks at the valve connection

Engineered to resist corrosion and impact in harsh under-vehicle environments, the 2701510-H11A2 bracket adopts a comprehensive protective system. The entire component undergoes shot blasting (Sa 2.5 grade) to remove impurities, followed by a 40μm cathodic electrophoretic primer for uniform rust prevention. The top layer is a 50μm high-adhesion polyester powder coating that withstands continuous exposure to road salt, mud, and diesel. This dual-layer system passes 2500-hour neutral salt spray testing (ASTM B117) with no red rust. The bracket’s edges are rounded (R4mm) to prevent stress concentration, and it can withstand gravel impacts up to 55km/h without denting, ensuring long-term structural integrity

Optimized to eliminate noise and prevent trailer valve damage from vibration, the bracket integrates dedicated dampening features. It includes 4mm-thick EPDM rubber gaskets between the bracket and trailer valve, as well as between the bracket and frame—absorbing 65% of chassis vibration (10-500Hz) and preventing metal-to-metal contact. These gaskets reduce operational noise to ≤45dB, eliminating the rattling sound common with unbuffered brackets. The mounting bolts use flange nuts with nylon inserts (self-locking torque ≥20N·m), which prevent loosening even after 100,000km of operation, avoiding the need for periodic re-tightening. A drainage hole at the bracket’s bottom prevents water accumulation and corrosion around the valve

This trailer valve bracket is designed for efficient installation and long-term cost savings for Dongfeng GX operators. The pre-assembled structure (bracket + rubber gaskets + grade 10.9 mounting bolts + lock washers) allows a single technician to complete replacement in 40 minutes using only a torque wrench (target torque: 130±10N·m)—no welding or drilling required. The OE-compatible design ensures perfect alignment with the trailer valve and frame, avoiding misfit issues of aftermarket brackets that cause air leaks or valve damage (repair costs up to $900). The high-strength steel and corrosion-resistant coating extend service life to ≥800,000km—twice that of non-OE alternatives. Backed by a 3-year/500,000km Dongfeng warranty, it provides reliable valve support and predictable maintenance expenses for fleets
