The working principle of electric pneumatic valve plastic balls

pneumatic ball valve is to rely on the working principle of pneumatic valve pneumatic valve love to make smooth rotation or occlusion. Pneumatic ball valve switch lightweight, small size, can make a large caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, has been widely used in various industries. Electric pneumatic valve plastic balls and cock pneumatic valve is belong to the same type of pneumatic valves, only its closure is a ball, the ball around the center line of the pneumatic valve body rotation to achieve a kind of pneumatic valves open and close. Pneumatic ball valve in the line is mainly used to do cutting, distribution, and change the flow direction of medium. Fluid resistance is small, its resistance coefficient with section of equal length. Simple structure, small volume, light weight. Compact and reliable, the pneumatic ball valve sealing surface material widely used plastic, good sealing characteristics, have been widely used in the vacuum system. Operation is convenient, open and close quickly, from open to close as long as the rotating °, is advantageous for the remote control. Pneumatic valve has simple structure, convenient maintenance, the ball sealing ring are generally activities, remove the replacement is more convenient. In full open or full close, the sphere and the pneumatic valve seat sealing surface and the dielectric isolation, medium through, can not cause erosion of pneumatic valve sealing surface. Applicability is wide and size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
