How does the electric butterfly valve work

Electric butterfly valve is composed of electric actuator and butterfly valve, so it has the advantages of easy operation and simple structure of butterfly valve, and is also widely used in chemical, pharmaceutical and other industries. And because of the assistance of electric actuators, the development of butterfly valves has reached a new level. The working principle of the electric butterfly valve: The valve stem is driven by the electric device to make the butterfly plate produce a 90° rotary motion to achieve the opening and closing of the valve.

The principle of the electric actuator is actually very simple. Just like a razor used in daily life, the energy source is electricity, and the electricity drives the operation of the valve plate, so as to open and close the valve and circulate or cut off the fluid. The electric actuator of the electric butterfly valve can be divided into switch type and adjustment type. The switch type electric butterfly valve plays the role of a switch; and the adjustment type electric butterfly valve plays the role of regulating the flow, which can accurately adjust the flow to thousands of degrees. It is also a relatively expensive valve.
