The reality of the role of the pneumatic V type ball valve pneumatic V type ball valve works rely on the rotary valve Love valves smooth or occlusion. Pneumatic ball valve switch is lightweight, small size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and the spherical often in the closed state, is not easy to be medium erosion, has been widely used in various industries. Pneumatic V type ball valve and plug valve is the same type of valve closure is a sphere, a sphere around the body centerline rotation to achieve open and closed a valve. Pneumatic V type ball valve in the pipe is mainly used to cut off the fast distribution and change the media flow direction. Pneumatic ball valve is a new type of valve in recent years has been widely used, it has the following advantages: 1. Fluid resistance is small, equal to the drag coefficient with the length of the barrel. Two. Simple structure, small size and light weight. 3. Reliable, close the valve sealing surface material widely used plastic, good sealing, has been widely used in the vacuum system. 4. Easy to operate, opening and closing rapidly, from fully open to fully closed as long as the rotation of 90 °, to facilitate remote control. 5 Easy maintenance, simple structure, pneumatic ball valves, and seals are generally activities, removal of the replacement is more convenient. 6. In the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, through the media, does not cause erosion of the valve sealing surface. 7. Wide scope of application, the path from childhood to a few millimeters to a few meters from the high vacuum to high pressure can be applied. Stainless steel pneumatic ball valves are widely used in various sectors of petroleum, chemical, power generation, paper, atomic energy, aviation, rockets, and people's daily life.
