The intelligent dual-flow solenoid valve is designed for use in computerized fuel dispensers to control two flow rates—high and low—enabling fast, efficient operation and precise metering of dispensed fuel. It is also suitable for rapid, efficient, and accurate metering of other liquids and gases. The valve is compatible with media such as gasoline, diesel, and kerosene, and features explosion-proof safety performance.
Unlike conventional solenoid valves, the intelligent dual-flow solenoid valve employs a microchip for control. It communicates with an external main control unit and, after protocol-based authentication, executes on/off control of the solenoid valve. Additionally, it incorporates an intelligent tamper-detection function: when strong magnets are used to attract the valve body in an attempt to cheat the system, the valve detects and logs the incident as evidence. Furthermore, thanks to an integrated rechargeable battery, the valve maintains a low-power intrusion-detection mode even when powered off or offline, enabling real-time monitoring. Compared with traditional solenoid valves, this design offers enhanced intelligence, unified control, and anti-tampering capabilities.
