Product overview

The close section hemispherical assembly of the side mounted eccentric hemispherical valve is installed from one side of the flange. This structure makes the maintenance more wear-resistant and easier to operate without dismantling the whole pipe. Side mounted eccentric hemispherical valve is a new generation of general ball silk. Because of its superior whole price ratio, it will be the best alternative to other ball valves in the future. The side mounted eccentric hemispherical Ti drives the shaft to rotate 90 ° with the help of the driving mechanism. At this time, the eccentric disc (hemisphere) fixed on the valve shaft rotates synchronously by 90 °. Rotate clockwise, the eccentric disc enters the valve seat, and Tong forms a wedge-shaped mechanism under the action of eccentricity. The valve disc gradually compresses the valve seat to realize sealing and close the valve. When rotating counterclockwise, the eccentric valve disc quickly disengages from the valve seat. When rotating 910 °, the valve is fully open.
