Design of a new mine-used part-turn electric valve controller

In order to improve intelligent level of electric valve controller, a new mine-used part-turn electric valve controller was designed. The controller uses absolute digital encoding technology to achieve high precision valve position detection, and uses current detection to achieve highly reliable function of over-torque protection of motor. Compared to conventional mine-used valve controller, the interface and control mode of the new controller are more flexible and intelligent level is higher.
