A brief description of the standard of regulating valve

·Regulating valve is currently in the field of automatic control. Whether a process can meet various process control indicators, whether the control process is stable, whether the overshoot, attenuation ratio, and disturbance are within the specified range, whether it is stable, fast, and accurate, in addition to the process In addition to the reasonable design, the important point is whether the control valve can act accurately according to the consciousness of the main body, so that the control consciousness of the main body of the process can be reflected in the accurate change of material energy and flow rate.

In many automatic controls, because the quality of the regulating valve is not good enough, the flow characteristics are poor, the leakage is large, and the action is unreliable, the automatic control loses high-quality adjustment, which brings heavy economic losses to production and increases labor intensity.

·Because the regulating valve is installed on the process pipeline and is in direct contact with the operating medium, it is affected by working conditions such as high temperature, high pressure, corrosion and friction for a long time. Therefore, the quality of the control valve selection has a great influence on the control effect of the system. Therefore, the correct and reasonable selection and installation of the regulating valve is very important.
