PFA Lined valves are widely used for corrosive fluid. ATW's PFA lined valves feature flexible seat design that effectively mitigates cold flow deformation of thermoplastic materials, ensuring smooth operation even at high temperatures. This design meets customers' requirements for corrosion resistance, zero leakage, long service life and easy operation. They are highly suitable for applications involving corrosive fluid such as sulfuric acid, hydrofluoric acid, phosphoric acid, strong alkalis, chlorine gas, as well as special gases and ultra-pure fluid in industries including lithium batteries, chlor-alkali, semiconductors and photovoltaics, metals and mining, basic chemicals, food and pharmaceuticals, and paper manufacturing. Antwei's lined valves precisely control compression to slow cold flow deformation of thermoplastics, preventing jamming at elevated temperatures and fulfilling strict industrial demands for reliability and performance.
