Product details

Overview of electric ventilation regulating butterfly valve:
The ZDLW and ZDRW electronic electric regulating butterfly valves are composed of a 3610R/L fully electronic electric actuator and a butterfly valve regulating mechanism. There is a servo system inside the actuator, so there is no need to install a separate servo amplifier. It has the characteristics of simple structure, high circulation capacity, and high adjustment accuracy. Suitable for regulating and controlling fluids containing suspended particles, as well as thick, turbid, and slurry fluids, widely used in industrial sectors such as petrochemicals, metallurgy, and power plants
