Electric butterfly valve flow resistance is small. Body internal media channel is direct, the medium flow in a straight line, small flow resistance. More energy when opening and closing. Is compared with the cut-off valve, because whether on or off, disc plate movement direction perpendicular to flow direction of medium. Its height is big, opening and closing time is long. Disc plate opening and closing of the trip is bigger, is through the screw. Water hammer is not easy to produce. The reason is closed a long time. Medium flows on both sides to any direction, easy to install. Electric butterfly valve on both sides of channel is symmetric. Structure length (the distance between the two connection end system shell) is smaller. Sealing surface wear easily, affect the service life. Open/close, two plate plate and valve seat sealing surface friction between sliding, to medium pressure cause abrasion wear easily, affect the sealing performance, shorten service life. Electric butterfly valve is one of the commonly used block valve is mainly used to connect or truncation pipeline in the medium, does not apply to adjust electric butterfly valve is suitable for the medium flow pressure, temperature and diameter range is very large, especially suitable for medium and large diameter pipeline.
