KATA API6D ECCENTRIC SEMI-BALL VALVE 24"

Eccentric semi-ball valve and flange valve belong to the same type of but the difference is that the closure member of eccentric semi-ball valve is a sphere and this sphere can rotate around the center line of the body to achieve the open and close movement. Ball valves are mainly used for cutting, distribution and changing the direction of the media flow in pipeline application. Two-piece ball valves and three piece ball valves are new kind of valves which have been widely used in recent years.

Eccentric semi-ball valves are suitable for waste water treatment, paper pulp, alumina, urban heating, as well as power plants, hydraulic slag removal or gas pipeline.

Eccentric semi-ball valve is composed of body, eccentric shaft, bonnet, spherical cap, axle sleeve, seat and other components. With 90 degree rotation by eccentric shaft, the valve can achieve open and close movements and plays a role in cutting off the media. Eccentric half ball valve can avoid the friction between the seat and spherical cap and because of the adoption of eccentric crank, there is an eccentricity between the center line of the spherical cap and valve runner. When the valve is open, the crank turns at a slight angle. At this moment, the spherical cap will leave the seat and having no more connection; on the contrary, in the close process, only in the close moment can the spherical cap contact with the seat.

With the advantage of simple structure, small size, light weight, convenient use, easy maintenance and other merits, eccentric semi-ball valve can be used in many industries with high efficiency. As The growing demand for this kind of valve, accelerating the development of eccentric semi-ball valves has been put on the agenda. We do believe that they are bound to make greater contributions to China’s economic construction in the future.
