The working power supply is usually: AC220V,AC380V, etc.Input signal: 4~20mA O-10v andother weak electrical signals. After the electric adjustment actuator and valve stem areconnected and debugged, the electric energy is used as the driving force to drive the hardseal butterfly valve plate for O~90° partial rotary movement.Receive 4~20mA signal fromthe industrial automation control system to precisely control the valve opening degree toachieve the regulation and control of different process parameters such as flow,temperature, and pressure.
