PRODUCT OVERVIEW
The intelligent electric single seat regulating valve is a balanced high-pressure differential electric regulating valve. It is equipped with intelligent integrated electric actuator, which receives the unified standard signal of 4-20mA or 1-5V · DC, converts the current signal into the corresponding linear displacement, and automatically controls the opening of the electric control valve to achieve the continuous adjustment of process parameters such as pressure, flow, temperature and liquid level of the fluid in the pipeline. The intelligent electric single seat regulating valve has the advantages of compact structure, light weight, good stability and high protection grade. It is widely used in automatic control systems such as large thermal power plants, chemical plants, water treatment and sewage treatment, natural gas oil fields, steel plants and so on.
