FCT PTFE Lined Check Valve

FCT PTFE Lined Check Valve

FCT PTFE Lined Check Valve – Clean Backflow Prevention in Corrosive Systems

FCT PTFE lined check valves feature a fully encapsulated interior lining made of PTFE or PFA, covering all wetted surfaces. This protects the valve body and components from corrosion while maintaining purity in systems carrying acids, alkalis, demineralized water, and hazardous fluids.

Their simple, automatic non-return action ensures leak-free shut-off upon flow reversal, making them ideal for chemical and high-purity industries.
