The triple offset design offers torque seating for tight shut off and minimal friction. Where traditional butterfly valve discs are in contact with the seat throughout the first 10 degrees of opening, the triple offset means that as soon as the valve begins to open, the disc surface moves away from the seat.

Less friction means not only less wear, but also less torque, and longer life. LINUO valves are used extensively in industries such as pulp and paper, chemical processing, petroleum, chemical fiber, powder processing, pharmaceutical, and environmental protection.
