Electric regulating butterfly valve
ZAJD type electric regulating butterfly valve has two kinds of switch type and intelligent type. Butterfly valve is matched with LKR actuator, and the operation can be controlled by inputting control signal (4~20mADC or 1 ~ 5VDC) and single-phase power supply. Electric regulating butterfly valve is small in size, reliable in performance, simple in matching and large in circulation capacity.
Electric regulating butterfly valve is suitable for medium is viscous, containing particles, fiber nature of the occasion. At present, the electric regulating butterfly valve is widely used in the industrial automatic control system of food, environmental protection, light industry, petroleum, paper making, chemical industry, electric power and other industries.
