HOME/V-NOTCH BALL VALVE-SERIES 300

V-NOTCH BALL VALVE-SERIES 300

The V–Notch Ball Valve gives non-clogging, high capacity, straight through flow control of fluids containing pulp and paper stock or slurries and fluids containing suspended solids or fibrous materials.
V-Notch Ball Valve is quarter turn valve with a segment Ball. The V-Ball create a wedging and shearing effect prevent the dragging of stock or slurry between the ball and its seal
The V- Notch Ball Valves are offered squared and clamped driven shaft plus ball shaft with splined connection designed for zero lost motion for highly accurate positioning and precise control.
