The intelligent electric control valve is a balanced electric control valve. By adopting a smart integrated electric actuator, it accepts analog 4-20 mA or 1-5 V•DC standard signal, which converts the current signal into a corresponding linear displacement, and then automatically controls the opening of the electric control valve, thereby it realizes continuous adjustment of process parameters such as pressure, flow, temperature and liquid level of fluid in the pipeline. The intelligent electric control valve has a compact structure, light weight, good stability and high protection level. Intelligent electric control valves are widely used in automatic control systems such as large thermal power plants, chemical plants, water treatment and sewage treatment, natural gas fields, and steel plants. As the world's leading manufacturer of actuators, this electric control valve has a worldwide reputation for its durable products. With decades of experience in installation and use in a variety of environments,this control valve has developed a highly reliable design.
