ZAJD Electric Butterfly Valve
ZAJD Electric Butterfly Valve
Product Features
There are two types of switches, switch type and intelligent type, which can be matched with butterfly valves and CWR actuators. They can be controlled by input control signals (4~20mADC or 1~5VDC) and single-phase power supply, offering strong functionality, compact size, lightweight design, reliable performance, simple installation support, and large flow capacity. This makes them especially suitable for handling viscous media containing particles or fibers. Currently, these valves are widely utilized in industrial automatic control systems across various sectors such as food processing, environmental protection, light industry, petroleum refining, paper production, chemical manufacturing, educational research facilities as well as electric power industries.
