Selection and use of pneumatic regulating valve in chemical

With the development of China's science and technology, automatic valves produced by China's chemical industry have been rapidly implemented, which can complete the accurate control of flow, pressure, liquid level and temperature. In the chemical automatic control system, the control valve is a main actuator, and its model and device quality have a major impact on the conditioning quality of the conditioning circuit, If the selection and use of the control valve is improper, it will seriously threaten the service life of the control valve, and even cause parking trouble in the system when the condition is serious. With the development of industrial automation, pneumatic control valve, as an outstanding actuator, has been widely used. This kind of control valve has the characteristics of reliable action and simple structure, which has a very important meaning to ensure the safety of the system,
