Dongfeng GX Gas horn solenoid valve assy 3754020-C6100

Equipped with a high-sensitivity electromagnetic coil (rated voltage: 12V DC, operating current: ≤1.2A), the solenoid valve achieves rapid on/off switching—response time is ≤0.15 seconds, ensuring the gas horn activates instantly when the driver presses the horn button. It supports a working pressure range of 0.6-1.0 MPa (matching Dongfeng GX’s air tank pressure), with a maximum air flow rate of 50 L/min—providing sufficient air supply to the gas horn for a loud, clear sound (115-120 dB) that meets national automotive horn noise standards (GB 7258). The valve core is made of high-wear PTFE material, ensuring stable air flow control without leakage

The solenoid valve body is constructed from aluminum alloy (ADC12) with a hard anodized surface treatment (thickness: ≥15μm), which resists corrosion from road salt, moisture, and oil stains—critical for under-vehicle or engine compartment installation. The coil housing uses high-temperature-resistant PA66 plastic (heat resistance up to 120°C), preventing deformation or insulation failure caused by long-term exposure to engine heat. The internal spring is made of 304 stainless steel, avoiding rust-induced jamming even in high-humidity environments, and extending the assembly’s service life to over 5 years

The entire assembly meets IP67 waterproof and dustproof standards. The electrical connector is sealed with a silicone O-ring, and the air port threads are equipped with nitrile rubber gaskets—effectively blocking water splashes, dust, and debris from entering the solenoid valve’s internal circuit and air channels. It can withstand 30-minute immersion in 1-meter deep water without leakage, and resists dust accumulation in off-road or construction site environments. This protection prevents short circuits in the coil or air leakage in the valve body, ensuring reliable operation in harsh weather conditions

The assembly adopts a bolt-fixed and quick-connect design: it is secured to the vehicle’s mounting bracket with 2 M8 bolts (matching original thread positions), and the air inlet/outlet ports use push-to-connect fittings (compatible with Dongfeng GX’s standard air hoses). No additional pipe cutting or thread tapping is required, and the electrical connector features a snap-in design for one-step connection. The entire installation process takes only 10-15 minutes with a basic wrench, reducing installation time by 40% compared to universal solenoid valves. The mounting holes are precisely positioned (error ≤0.3 mm), ensuring accurate alignment with the vehicle’s original bracket
