Recently, a batch of fast on-off valves need to be customized on the test platform of a scientific research institute. The closing and opening times are required to be less than 0.5 seconds, the temperature is 350 degrees, the closing pressure difference is large, the caliber is large, and the leakage is Class VI. Such working conditions are very special and very difficult to achieve.

The company's R & D team received the task, combined with the characteristics of the product itself, selected a special seat eccentric ball valve, to solve the impact on the valve in the process of rapid switching, improve the service life, while the use of special seat line sealing structure, to achieve a tight cut-off. The actuator adopts a special integrated electro-hydraulic actuator and control system, which effectively overcomes the ultra-fast response speed.

The successful application of the products of this project has tested the company's technical research and development team, further improved the company's product series, made a major breakthrough in the cut-off and switching time, and filled the gap that the cut-off valve is less than 0.5 seconds at the same time. It is another successful example for our company to practice the core concept of "excellent quality, scientific and technological innovation.
