果冻传媒 Eccentric Half Ball Valve
Eccentric half ball valves are suitable for waste water treatment, paper plant, chemical treatment, oil & gas pipeline, as well as power plants, hydraulic slag removal.
With 90 degree rotation by eccentric shaft, the valve can achieve open and close movement 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.
