Dongfeng GX truck parts Electromagnetic valve assembly 3754110-H18A0

Designed to regulate fluid pressure/flow in Dongfeng GX trucks’ critical systems (e.g., air brakes, automated manual transmission), this assembly features a high-performance solenoid coil with 12V/24V (matchable to Dongfeng GX’s electrical system) operating voltage. The coil delivers fast response time (≤0.03 seconds) to ECU signals, enabling instant on/off switching or pressure adjustment—critical for applications like brake actuation or clutch control where delay could impact safety. It also maintains stable magnetic force under varying electrical loads (9–32V), ensuring consistent performance even in voltage fluctuations common in truck electrical systems. The valve core is crafted from hardened stainless steel, minimizing internal friction and ensuring precise flow control (flow rate accuracy ±2%), preventing over-pressurization or insufficient fluid supply to downstream components

Built to withstand the harsh operating conditions of commercial trucks (vibration, temperature extremes, dust), the assembly uses rugged materials for long-term reliability. The valve body is made of high-strength aluminum alloy with an anodized surface treatment, offering excellent corrosion resistance (withstanding 500 hours of salt spray testing) and impact resistance (able to absorb 15J of energy without cracking). Internal seals are made of high-temperature-resistant FKM (Viton) rubber, which maintains elasticity and sealing performance in temperatures ranging from -40°C (cold winters) to 150°C (engine bay heat), avoiding seal degradation or fluid leaks. The solenoid coil is encapsulated in flame-retardant epoxy resin, protecting it from dust, moisture, and oil contamination—extending the assembly’s service life to over 10,000 operating hours

This assembly integrates comprehensive safety features to protect both the truck’s systems and operators. It includes a built-in pressure relief valve that automatically diverts excess fluid when pressure exceeds 1.2x the rated value (adjusted to Dongfeng GX’s system specifications), preventing damage to hoses, pumps, or other components. The electrical circuit features overcurrent protection (via a built-in fuse) that cuts power to the solenoid coil if current exceeds 5A, avoiding coil burnout or electrical short circuits. Additionally, the valve body is designed with a fail-safe position (e.g., spring-return to “closed” for brake systems) that activates if electrical power is lost, ensuring critical systems like brakes remain functional—reducing the risk of accidents during power failures. These safety features meet international commercial vehicle standards (ISO 13849, SAE J1939), ensuring compliance with truck safety regulations

Engineered for user-friendly deployment and upkeep in truck repair scenarios, this assembly simplifies maintenance workflows. It comes with pre-assembled mounting hardware (high-tensile bolts, lock washers) and a color-coded fluid line label, allowing technicians to identify inlet/outlet ports quickly and complete installation in 30 minutes or less. The valve body features a compact design (optimized for Dongfeng GX’s under-chassis space) that avoids interference with adjacent components like fuel tanks or exhaust systems. For maintenance, the assembly uses a modular design: the solenoid coil can be replaced independently without removing the entire valve body, reducing repair time and cost. It also includes a diagnostic port compatible with Dongfeng GX’s OEM scan tools, enabling technicians to check valve status (e.g., coil resistance, switching frequency) and troubleshoot issues without disassembly. Backed by a 24-month warranty against manufacturing defects, this assembly minimizes truck downtime for fleet operators
