The valve manipulator adopts semiconductor sensor with high stability and small sensitivity drift, supports sensor failure detection, microprocessor control, etc. This electric valve controller adopts electric-manual changeover clutch, so that the robot automatically opens the valve and presses the electric switch, which is safe and reliable. This valve intelligent controller adopts DC or AC 12V safety voltage, automatic valve closing action is fast, and adopts insulated shell, good sealing and little interference. This WIFI pipeline shut-off valve is mainly used in places where combustible gases (LPG, naturally gas, biogas, etc.) may leak to ensure life safety. If you have any questions, please feel free to contact us. The intelligent valve controller is widely used for the automatic control of gas pipeline balls valves, gas cylinder balls valves, various connection alarms, gas liquids and other valves.
