PRODUCT DESCRIPTION
Genuine Precise Braking Control & Leak-Proof Design
This hand control valve assembly (OE:3517910-T38V0) adheres to Dongfeng’s genuine manufacturing standards, crafted from high-strength metal alloy (resists corrosion from road debris) and premium sealed rubber components. It delivers precise modulation of the truck’s braking system, allowing drivers to adjust braking force smoothly—critical for heavy-load transport. Unlike aftermarket valves, its factory-calibrated internal structure ensures 0 hydraulic leakage under 10bar pressure, maintaining consistent braking performance across long-haul trips.
Reliable Braking & Incompatible Aftermarket Valve Issues
It is 100% compatible with Dongfeng KL’s braking system (cross-check OE 3517910-T38V0 for fitment). The valve solves common pain points: generic valves that have unresponsive braking (increasing accident risk), leaky seals that waste hydraulic fluid, and misaligned mounts that cause rattling. It ensures consistent braking response in all weather conditions, reducing fleet maintenance costs related to braking system failures by 90%.
Certified Durability & Fleet-Tested Reliability
As a critical braking component, this valve has passed Dongfeng’s strict quality audits and third-party performance tests: it retains full functionality after 10,000+ operation cycles (fleet test data) and resists corrosion in salt-spray environments for 500+ hours. It complies with commercial vehicle braking safety regulations (ECE R13), ensuring legal and safe operation for your Dongfeng KL fleet.
