Pneumatic three-piece ball valve advantages
Pneumatic three-piece ball valve and plug valve are of the same type of valve, and only its closure is a ball, the ball around the centerline of the valve body to rotate to achieve the opening and closing of a valve. Pneumatic three-piece ball valve in the pipeline is mainly used to cut off fast, distribution and change the flow direction of the media. Pneumatic three-piece ball valve is widely used in recent years, a new type of valve, which has the following advantages: 1. Pneumatic three-piece ball valve fluid resistance is small, the coefficient of resistance and the same length of pipe equal. 2. Simple structure, small size, light weight. 3. Tight and reliable, the current ball valve sealing surface material widely used plastic, good sealing, vacuum system has also been widely used. 4. Pneumatic three-piece ball valve easy to operate, open and close quickly, from full to complete turn as long as 90 °, easy to remote control. 5. Easy maintenance, pneumatic valve structure is simple, the seals are generally active, demolition and replacement are more convenient. 6. In the fully open or fully closed, the ball and valve seat sealing surface and media isolation, the media will not cause erosion of the valve sealing surface. 7. Pneumatic three-piece ball valve wide range of applications, diameter from a few millimeters, up to a few meters, from high vacuum to high pressure can be applied.
