Electric Butterfly Valve Working Principle

- Oct 20, 2018-

Electric butterfly valves are generally connected to the most common electric wafer type butterfly valve and electric flange butterfly valve.

The sealing material has soft seal (normal temperature and normal pressure) and hard seal (high temperature and high pressure). The working power supply usually has: AC220V, AC380V, DC24V, input signal has 4~20mA 0~10v and other weak electric Signal, and finally according to the control form For the switch type and the adjustment type, the switch type functions as a switch; the adjustment type is used to adjust the flow rate, and the flow rate can be accurately adjusted to a thousand degrees, Which is also a relatively high price valve.

The electric butterfly valve uses electric energy as the driving force to drive the valve stem through the electric device, so that the butterfly plate generates 90° rotary motion to achieve the opening and closing of the valve, and can also receive 4~20 mA or Other signals of the industrial automation control system to accurately control the valve opening degree. In order to achieve the regulation and control of different process parameters such as flow, temperature and pressure.
