FCT Concentric Butterfly Valve

FCT Concentric Butterfly Valve

FCT Concentric Butterfly Valve – Cost-Effective Shut-Off for General Service

FCT concentric butterfly valves feature a centered disc and rubber or elastomer seat which together provide bubble-tight shut-off in low to medium pressure applications. The disc rotates 90 degrees between open and closed positions, enabling fast operation with minimal torque.

With body styles available in wafer and lug type, these valves are widely used in water distribution, HVAC systems, chemical services, and light industrial processes.
