Product Description Product DescriptionRQ, RQM series intelligent electric actuators are a new generation of intelligent products. Advanced ultra-large-scale digital integrated chips, digital torque sensors and digital displacement sensors, full Chinese menu operation and display, and mechatronic structural design have created its excellent performance, light and beautiful, simple debugging, and convenient operation. It is more suitable for matching with various valves to form an execution unit, and is used in automatic control systems such as power stations, petroleum, steel, chemicals, oil pipelines, and sewage treatment. It can meet both frequent adjustment control and intermittent control requirements.
