V- type ball valves

V- type ball valve is a spherical core channel is designed to a open“V”shape of the valve, with accurate flow characteristic and control function. Through 0-90 degrees rotation, to achieve the adjustment of the flow rate. No clearance friction between the valve seat and spherical surface, with excellent shear force and self-cleaning ability, especially suitable for fluid medium with fibers or with small particles .
