What are the common classifications of VEHICLE BRAKE VALVE?

In the vehicle's braking system, the brake valve, as a key control element, undertakes the important task of regulating and distributing the brake fluid pressure. According to its working principle and application scenarios, VEHICLE BRAKE VALVE can usually be divided into multiple categories.

1. According to the working principle, it can usually be divided into hydraulic brake valves and pneumatic brake valves. The hydraulic brake valve controls the action of the brake through the flow and pressure changes of the hydraulic oil. It is the most common type in modern automobile braking systems. The hydraulic brake valve has the advantages of fast response speed, uniform braking force, and easy automatic control. It uses the pressure generated by the hydraulic pump to transfer the hydraulic oil to the brake through the brake line to achieve the braking effect. The pneumatic brake valve uses compressed air as the working medium and achieves braking by controlling the on and off of the airflow and the pressure change. This type is more common in heavy vehicles such as large commercial vehicles and trailers. The air brake valve has the characteristics of simple structure, easy maintenance and large braking force. It uses the compressed air stored in the air cylinder to control the charging and discharging of the brake cylinder through pipelines and valves, thereby driving the brake shoe or brake disc for braking.
2. According to the functional classification, it can usually be divided into main brake valve, proportional valve and load sensing valve
The main brake valve is the core control element of the braking system, which is responsible for receiving the driver's braking instructions and distributing the brake fluid pressure to the brakes of each wheel. The main brake valve usually has multiple outlets, which are connected to different brake lines to ensure the balance of braking force of each wheel.
The proportional valve is used to adjust the braking force distribution ratio between the front and rear wheels or the left and right wheels to meet the needs of different road conditions and vehicle load conditions. The proportional valve automatically adjusts the braking force distribution ratio by sensing the vehicle's posture and acceleration information to improve braking stability and safety.
Load sensing valve. The load sensing valve is mainly used in heavy vehicles to automatically adjust the size of the braking force according to the change of the vehicle load to ensure the consistency of the braking effect. The load sensing valve judges the load state by sensing the deformation of the vehicle suspension system and adjusts the size of the braking force accordingly.

VEHICLE BRAKE VALVE can be divided into multiple categories according to different working principles and functions. These different types of brake valves perform their respective duties in the vehicle braking system and work together to ensure that the vehicle can achieve safe and reliable braking effects under various working conditions. With the continuous development of automobile technology, the performance and functions of vehicle brake valves are also constantly improving and perfecting, providing drivers with a safer and more comfortable driving experience.
