Concentric butterfly valves are constructed with a stem travelling along the midline of the valve disk and lack any offsets. With a full diameter structure, our concentric butterfly valves reduce flow resistance and ensure fluids smoothly pass through the valves.
As they are made with fewer components, concentric valves are easier to set up due to their lightweight frame and are more affordable variants. Along with efficient technical support and 2-year product warranty, we provide excellent after-sales tracking to ensure our customers’ satisfaction.
