1. Products instruction

FLS-YCKZ/03 series intelligent electric differential pressure regulating valve is consist of pressure sensor, V type ball valve, and intelligent valve actuator.

Operating principle: Set the differential pressure value in intelligent valve actuator first, and these two pressure sensors test the real differential pressure value in pipe to  contract the pre-set value that control by PID. Finally, the intelligent valve actuator regulate the valve open degree  to stabilized the differential pressure valve.  The intelligent electric differential pressure regulating valve is suitable for heat ventilation and air-conditioning, building automation, chemical industry, energy, fire protection, environmental protection, pharmacy etc.
