Product Description
Our PTFE lined ball check valve is a one-way valve that automatically opens and closes based on the pressure of the medium itself. The valve body is lined with fluoroplastic (PTFE, FEP, or PFA), effectively preventing corrosion of the metal parts by corrosive media such as acids, alkalis, and strong oxidants, ensuring long-term stable operation in harsh chemical environments.
Our PTFE lined ball check valve features a compact structure, sensitive opening and closing, and superior sealing performance. It is widely used in pipeline systems handling corrosive media in the chemical, pharmaceutical, metallurgical, papermaking, electroplating, and environmental protection industries to prevent backflow that could damage or contaminate equipment.
