Multi turn intelligent valve electric device with 4-20mA input and output signals is suitable for valves with linear movement of valve plate, such as gate valve, stop valve, etc., which can realize remote control, centralized control and automatic control of the valve. The valve electric device has double limit and double protection of torque and travel, more opening indication shows the switching value of the valve, with complete functions, reliable performance and advanced control system, so that It is easy to use and maintain. The intelligent type has the functions of automatic phase sequence identification, automatic fault diagnosis, super large liquid crystal display and so on. It is widely used in electric power, metallurgy, petroleum, chemical industry, papermaking, coal, water supply and drainage and other departments.



The product has the basic functions of liquid crystal display and control, valve position feedback, remote signal isolation, and adopts electronic zero adjustment and full adjustment technology to replace the traditional method of repeated potentiometer adjustment, which can easily calibrate the opening 0% and 100% positions. It can output 4-20mA switch control signal and receive 4-20mA analog control signal. It can visually display the valve opening percentage, on-site, remote status and switch position status, and indicate faults.
