This series of intelligent electric regulating valves is a pressure balanced electric intelligent regulating valve. Equipped with an intelligent electric actuator, it receives a unified 4-20mA or 1-5V · DC standard signal, converts the current signal into a corresponding linear displacement, automatically controls the opening of the regulating valve, and achieves continuous adjustment of process parameters such as pressure, flow rate, temperature, and liquid level of the fluid in the pipeline. The intelligent electric regulating valve has a compact overall structure, light weight, good stability, and high protection level. So electric intelligent regulating valves are widely used in automatic control systems such as large thermal power plants, chemical plants, water and sewage treatment, natural gas oil fields, steel plants, etc.
