Description
Series 8200FV V-Ball Valves are Quarter Turn Valves with a segment Ball. Its V-notch Ball design provides accurate and reliable control in a wide range of applications. It is ideal for Throttling Control of plup and paper stock, slurries and fluids containing suspended solids or fibrous materials. In operation, the V-Ball creates a wedging and shearing effect, prevents the dragging of stock or slurry between the ball and its seal. The straight through flow path provides high capacity for gases, liquids and fibrous materials.
