C Type Eccentric Frictionless Ball Valve

◆ Type C ball valve has simple structure, good sealing performance, small volume, light weight, less material consumption, and simple operation within a certain nominal diameter range. Newlotoke adds eccentric design to the ball valve of C-type ball valve. Realizing the frictionless rotation of the ball during the opening and closing process of the ball valve, it can also effectively avoid the wear of the ball and the surface of the valve seat, and can reduce the torque carried by the valve stem and the actuator, and at the same time reduce the requirement for the strength of the valve stem.

◆ No flow resistance DC channel,

◆ The flow channel is unobstructed without dust accumulation or jamming,

◆ The pressure loss is small, and the medium will not deposit in the valve cavity;

◆ Due to the principle of eccentricity, the eccentric hemisphere is completely separated from the valve seat when opening, without any contact,

◆ The opening and closing torque is small, the opening and closing can be completed by turning 90 degrees, and the operation is light and convenient;

◆ When the valve is closed under the action of double eccentricity, the eccentric hemisphere and the valve seat become tighter and tighter, which fully achieves a good sealing purpose;

◆ The eccentric hemisphere of the hemispherical cut and the valve seat have shearing and squeezing effects, which can effectively remove the scale or dirt on the sealing surface and maintain a good seal.

◆ There is no friction between the eccentric hemisphere and the valve seat, which effectively overcomes the problem of constant friction between the ball sealing surface and the valve seat sealing surface of the traditional ball valve, so the sealing surface is well protected.
