1.Precise Regulation: Enables proportional flow adjustment (not just on-off control), making it suitable for process scenarios with high requirements for flow accuracy. 2.Intelligent Controllability: Supports communication protocols such as 4-20mA signals and Modbus; can be integrated into PLC/DCS systems to realize remote monitoring. 3.Wide Applicability: No air supply required, suitable for working conditions with sufficient power and no compressed air
