ZAJD type electric regulating butterfly valveDetailed product description：

The ZAJD electric butterfly valve has two types: switch type and intelligent type. The butterfly valve is matched with the CWR 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 valve is widely used in industrial automatic control systems in industries such as food, environmental protection, light industry, petroleum, papermaking, chemical engineering, teaching and research equipment, and power.
