1、 Introduction to ZAJD Electric Butterfly Valve Body

ZAJD型电动蝶阀尺寸图

ZAJD electric butterfly valveThere are two types: switch type and intelligent type. The butterfly valve is matched with the DTR actuator and inputs control signals (4)～20mADC or 1～5VDC) and single-phase power supply can be used to control the operation, with strong functionality, 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.气动三偏心蝶阀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.
