FCT Eccentric Butterfly Valve

FCT Eccentric Butterfly Valve

FCT Eccentric Butterfly Valve – Reduced Friction, Improved Longevity

FCT eccentric butterfly valves utilize a single-offset design, where the shaft is placed behind the centerline of the disc, reducing seat contact during opening and closing. This results in lower operating torque, reduced wear, and longer seat life, making the valve suitable for both on/off and modulating control.

These valves are offered with resilient or metal seats, depending on the pressure, temperature, and media requirements, and are widely used in water treatment, oil & gas, chemical processing, and energy sectors.
