Electric fluorine lined regulating butterfly valve
Model and specification DYH971F46 nominal diameter 50-400mm pressure range 1.0, 1.6, 2.5MPa suitable for corrosive media
Product details
main features
DYH971F46 electric fluorine lined regulating butterfly valve has two types: switch type and intelligent type. The butterfly valve is matched with YHR actuator and can be controlled by inputting control signals (4-20mADC or 1-5VDC) and single-phase power supply. It has strong functions, small size, lightweight and pleasant, reliable performance, simple matching, and large flow capacity, especially suitable for occasions where the medium is viscous, contains particles, or fibers. At present, this electric regulating valve is widely used in industrial automatic control systems in industries such as food, environmental protection, light industry, petroleum, papermaking, chemical industry, teaching and research equipment, and power.
