The characteristics of pneumatic ball valve in the valve

Ball valve is one of special valve in the pipeline, indeed because of open-close part is a sphere, this form of pneumatic valve is not so potent sealing effect. But due to the access of the pneumatic actuators this ball type valve can realize automatic adjustment role in pipeline, and a lot of times, it does not do this type of valve in the pipeline in half closed form, generally after the ball type valve can only rotate in the pipeline, full open and close. Pneumatic ball valve in the line is mainly used to do the cutting speed, distribution, and change the flow direction of medium. Pneumatic ball valve is a new kind of valve, the most widely used in recent years has the following advantages: small fluid resistance, the resistance coefficient with section of equal length. Simple structure, small volume, light weight. Compact and reliable, the ball valve sealing surface material widely used plastic, sealing good, also has been widely used in the vacuum system. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control. http://www electric ball valve manufacturer. dazkfy。 com
