FCT PTFE Lined Butterfly Valve

FCT PTFE Lined Butterfly Valve – Compact Corrosion Control with Smooth Flow

FCT PTFE lined butterfly valves feature a concentric disc design with a fully encapsulated PTFE seat and disc, making them ideal for handling aggressive chemicals, acids, and ultrapure fluids.

The non-stick, chemically inert PTFE lining ensures maximum resistance to corrosion while allowing for bubble-tight sealing, low torque operation, and long service life—especially in environments where metal contamination must be avoided.
