As the "dispatch center" of the power system, the control valve realizes the refined control of power by adjusting key parameters such as fuel injection quantity, air intake quantity and transmission oil pressure. When the truck is faced with the test of heavy load climbing, it can quickly sense the change of engine load, immediately increase fuel supply and optimize the air intake ratio, so that the power output is continuously strong, helping the vehicle easily climb over steep slopes; When cruising on a flat road, it will automatically reduce the fuel supply, stabilize the engine in the economic speed range, significantly reduce the fuel consumption per 100 kilometers, and realize the flexible switching between power and economy.

In the field of safety protection, the control valve plays the role of the "first line of defense". In the braking system, the ABS anti-lock control valve can quickly adjust the brake pipe pressure in milliseconds once it finds that the wheel tends to lock by monitoring the speed change of each wheel in real time, so as to achieve the "point brake" effect, effectively prevent the vehicle from skidding and losing control, and greatly improve the braking safety especially on rainy and snowy slippery roads; In the hydraulic lifting system, the pressure control valve strictly controls the pressure range of hydraulic oil. When the pressure exceeds the safety threshold, it immediately cuts off the oil circuit to avoid the deformation and fracture of the lifting device caused by excessive pressure, ensuring the safety of cargo loading and unloading.

With the integration of intelligent technology, the modern control valve has been upgraded to an "intelligent decision-making assistant". It is equipped with advanced electronic sensors and intelligent algorithms, which can collect a large amount of data such as road conditions, load, vehicle speed and engine temperature in real time, and dynamically adjust the working strategy accordingly. For example, when driving on a rugged mountain road, it can predict the change of vehicle slope in advance, and link with the transmission control system to accurately adjust the shift timing, reducing the frustration caused by power interruption; On continuous downhill sections, by controlling the opening of the exhaust brake valve, the engine's reverse drag effect is used to assist deceleration, reducing the wear of brake pads, prolonging their service life, and at the same time reducing the risk of thermal attenuation caused by frequent braking, indirectly reducing maintenance costs.

In order to cope with the complex and changeable working environment of trucks, the control valve is ingenious in design and material. The main body is forged from high-strength alloy steel, which has excellent impact resistance and deformation resistance; The sealing parts are made of oil-resistant and high-temperature-resistant special rubber materials, which can maintain good sealing performance in the extreme temperature range of -40℃ to 120℃, and effectively resist the erosion of oil and dust. Even in the continuous vibration of long-distance transportation, the dusty environment of mining operations or the low-temperature conditions in cold regions, it can always maintain stable working performance, ensure accurate "instructions", and provide a solid guarantee for the long-term and reliable operation of trucks.
