The main advantage of the metal hard seal ball pneumatic valve

pneumatic ball valve available Yu Shiji s, with the rapid development of science and technology, the continuous improvement of production technology and product structure, in the short years, has rapidly developed into a major pneumatic valve class. Industrial developed country in the western countries, the use of pneumatic ball valve is constantly rising year by year, in our country, pneumatic ball valve is widely used in petroleum refining, long pipeline, chemical industry, paper making, pharmacy, water conservancy, electric power, municipal, industries such as steel, holds the pivotal status in the national economy.
pneumatic ball valve is mainly used to cut or connect line in the medium, can also be used on regulation and control of fluid, including hard seal V pneumatic valve the v-shaped ball core of carbide surfacing with strong shear force between metal pneumatic valve seat, especially suitable for fiber, micro solid material such as medium. And more general pneumatic ball valve on the pipe not only can the confluence of flexible control medium, shunt, and the flow switch, at the same time also can close any channel and make the other two.

working principle of the pneumatic valve ball pneumatic valve it has a rotation motion, the cock body for a sphere, a round hole or tunnel through its axis. Pneumatic ball valve in the line is mainly used to do cutting, distribution, and change the flow direction of medium, it only need to use rotation operation and small rotational torque can be closed tightly. Pneumatic ball valve is suitable to do the most switch, cut off the pneumatic valve is used, but recent development has pneumatic ball valve designed to make it with throttling and control flow, such as pneumatic valve v-shaped ball.
pneumatic ball valve itself is the main characteristics of compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, easy operation and maintenance, and is applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, widely used in various fields. Pneumatic valve pneumatic ball valve body can be as a whole, also can be combined. Fluid resistance small, full size of the pneumatic ball valve with little flow resistance. Simple structure, small volume, light weight. The compact and reliable. It has two sealing surface, and the pneumatic ball valve sealing surface of materials widely used all kinds of plastic, good sealing, can realize completely sealed. Have been widely used in the vacuum system. Easy to operate, 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. Due to the pneumatic ball valve in the opening and closing process is wiped, so can be used to bring in the medium of suspended solid particles
