In the modern industrial system, the hydraulic system is widely used in various fields such as construction machinery, mining machinery, and shipbuilding due to its advantages of efficient and stable power transmission. The brake valve, as a crucial part of the hydraulic system, is of no little importance.
1.Ensuring equipment operation safety
Equipment driven by the hydraulic system usually has large loads and high speeds. If an accident occurs and the braking cannot be carried out in time, it is very likely to cause serious safety accidents. The brake valve can provide precise braking force in normal working conditions, allowing the equipment to stop smoothly according to the operator’s intention, avoiding runaway inertia; in emergency situations such as power failure, by adjusting the brake valve in the forward direction and coordinating with components such as accumulators, it can respond quickly and achieve emergency braking. For example, during mining operations, large equipment such as excavators rely on the brake valve to stop in time in case of sudden failures, preventing equipment from sliding or losing control, and ensuring the safety of workers and equipment property.
2.Ensuring precise and stable operation
The operation of the hydraulic system requires precise control, and the characteristics of the brake valve directly affect the accuracy and stability of the operation. Its compact structure allows it to be installed in narrow spaces without affecting the overall layout of the hydraulic system, and it can also closely cooperate with other components. Moreover, it has a comfortable foot feel, rapid pressure response, and smooth adjustment, allowing operators to accurately control the braking force according to the actual working conditions. Take the crane in construction machinery as an example. During lifting operations, the brake valve can precisely stop the lifting arm at the designated position, avoiding instability in braking that may cause the heavy object to shake or even fall, improving operation quality and efficiency.
3.Adapting to diverse working environments and conditions
Hydraulic systems in different industries face diverse working environments and conditions. The performance parameters of the brake valve determine its adaptability. The following table shows the key parameters of the brake valve and the corresponding adaptation scenarios:
| Parameter Type | Specific Parameters | Adaptation Scenarios |
| Working Medium | Mineral – based Hydraulic Oil | Covers most industrial hydraulic systems and has strong compatibility. |
| Viscosity Range | 2.8 – 380mm²/s | Can operate stably in scenarios such as cold outdoor in northern regions (low viscosity requirement) and high – temperature industrial workshops (high viscosity requirement). |
| Hydraulic Oil Temperature Range | - 30℃ to 107℃ | Adapts to various complex working conditions from extremely cold to high temperature. |
| Pressure Setting Range | 20 – 200bar | Meets the braking requirements of different loads and intensities, from fine braking of light – duty equipment to strong braking of heavy – duty machinery. |
| Maximum Input Pressure of the Whole Series | 210bar | Provides sufficient braking power support for hydraulic systems with high – pressure requirements. |
4.Enhance the reliability and service life of the system
The brake valve has strict requirements for cleanliness (reaching levels of 18/16/13, ISO4406), and also limits the maximum return oil pressure to no more than 1 bar. This helps maintain the cleanliness and stability of the hydraulic system. A clean system environment reduces the wear of hydraulic components by impurities, and stable return oil pressure avoids shock to the system caused by pressure fluctuations, thereby reducing the failure rate of the entire hydraulic system, extending the equipment’s service life, reducing enterprise maintenance costs and downtime, and ensuring production continuity.
The brake valve plays a crucial role in the hydraulic system in terms of safety assurance, operation control, environmental adaptation, and system reliability. It is an indispensable key component for the stable, efficient and safe operation of the hydraulic system. With the continuous development of industrial technology, the requirements for the performance of the brake valve will also continue to increase. The brake valve will also be constantly innovated and upgraded, providing more powerful support for the development of the hydraulic system.
