Product Overview
The PTFE Lined Ball Valve is a corrosion-resistant valve specially designed for strong acid, alkali, and chemical media.
The valve body, ball, and seat are fully lined with fluoroplastic materials (PTFE, PFA, or FEP) to completely isolate the process fluid from the metal body, ensuring excellent resistance to chemical corrosion and zero leakage.
This valve is ideal for chemical, pharmaceutical, chlor-alkali, and environmental protection systems, where long-term stability and safety are critical.
