Principle of electric butterfly valve:

The valve stem is driven by an electric device to make the butterfly plate produce a 90° rotation movement to achieve the opening and closing of the valve. The principle of the electric actuator is actually very simple. Just like the daily razor, the energy source is electricity. 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 the switch; while the adjustment type electric butterfly valve plays the role of adjusting the flow rate, which can accurately adjust the flow rate to micrometers. It is also a relatively expensive valve. As a device installed in the pipeline, the valve does not seem to be very realistic if the on-off state is checked on the spot, so there is a feedback signal. The adjustment type itself has a feedback signal, and the switch type can choose whether to install the feedback signal according to the specific needs of the customer.
