Dongfeng KL truck spare parts Quick release valve 3533010-90001

Built as a critical component for brake system efficiency, this quick release valve delivers ultra-fast pressure relief to ensure timely brake release and smooth vehicle operation. When the driver releases the brake pedal, the valve exhausts 90% of the compressed air from the brake chamber in ≤0.3 seconds—30% faster than standard valves—eliminating brake drag (a common cause of overheating and pad wear). It features a precision-machined poppet valve with a 15mm diameter, maximizing exhaust flow rate (≥50L/min) while maintaining stable pressure control during brake application. The valve’s pressure response threshold is calibrated to 0.4MPa, ensuring it only activates when the brake pedal is fully released, preventing accidental pressure loss. For Dongfeng KL trucks, this rapid response reduces stopping distance by 5% and extends brake pad life by 25%

Engineered for consistent and reliable operation, the 3533010-90001 valve features a high-precision internal design. The valve core is made of wear-resistant PTFE (polytetrafluoroethylene) with a self-lubricating surface, reducing friction and ensuring smooth movement over 1 million cycles. A stainless steel return spring (304 grade) provides consistent force (5-7N) to reset the poppet valve, avoiding sticking caused by dust or moisture. The valve body’s internal channels are CNC-machined with a surface roughness of Ra 0.8μm, minimizing air flow resistance and pressure loss (≤0.02MPa). A built-in filter screen (100μm mesh) prevents particulate matter from entering the valve core, avoiding jamming and ensuring long-term performance in dusty construction environments

Optimized to withstand the extreme conditions of truck chassis operation, the quick release valve features a rugged, corrosion-resistant construction. The valve body is precision-cast from ADC12 aluminum alloy with a 3mm wall thickness, achieving a tensile strength of 180MPa and resisting impact from road debris. The surface undergoes a hard anodizing treatment (15μm thickness) and a clear protective coating, passing 2000-hour neutral salt spray testing (ASTM B117) with no corrosion. All threaded interfaces use nickel-plated brass inserts, ensuring secure connection with brake pipes and resisting galling. The valve operates stably within a temperature range of -40℃ to 120℃, adapting to frigid northern winters and high-temperature brake system environments

This quick release valve delivers significant cost savings and maintenance convenience for Dongfeng KL operators. Its rapid pressure release reduces brake system wear, cutting brake pad and drum replacement costs by 25% (saving $600+ per vehicle annually). The OE-compatible design ensures perfect integration with the brake system, avoiding mismatched valves that cause brake failure (repair costs up to $2,000) and regulatory fines. The valve’s modular structure allows a single technician to complete replacement in 45 minutes using standard tools, minimizing downtime. The built-in filter screen is removable for cleaning, extending the valve’s service life to ≥300,000km—three times that of aftermarket alternatives. Backed by a 1-year/150,000km Dongfeng warranty, it provides reliable brake system performance and predictable maintenance expenses for fleet operations
