FCT PTFE Lined Diaphragm Valve

FCT PTFE Lined Diaphragm Valve – Hygienic and Corrosion-Resistant Flow Control

FCT PTFE lined diaphragm valves feature a weir-type or straight-through body with full PTFE or PFA lining and a flexible PTFE diaphragm that isolates the valve body and actuator from the process fluid. This design guarantees leak-free, metal-free flow paths—especially important for ultra-clean or chemically aggressive media.

They provide both on/off and throttling service, while their cavity-free interior reduces dead zones and contamination risks.
