Electric V ball valve, the ball core is V shape, can realize linear adjustment, adjustable range is large. When the valve is closed, the v-shaped notch and the seat between the wedge shear function, both have the self-cleaning function and prevent the ball core card dead, especially suitable for the pipeline fouling freezing occasion. Suitable for the control of pulp and sewage, containing fiber and granular solid suspension media and powder granular media.
