Electric flange butterfly valve

電動法蘭蝶閥Composed of an electric actuator and a flange butterfly valve, it can be divided into switch control type and intelligent adjustment type (4-20mA analog signal control) according to different working modes and conditions. The sealing forms include soft seal and hard seal. Through the operation of the electric actuator, the rotating valve stem drives the disc plate to open and close within the range of 0-90 °. The structural performance of electric flange butterfly valves is superior to that of clamp type butterfly valves, and they generally have higher pressure resistance. It is recommended to use electric flange butterfly valves for working conditions with a diameter exceeding DN600.
