PTFE Lined Butterfly Valves

4Matic PTFE lined valves are well suited for consistent performance requirements in highly corrosive applications involving chlorine, benzene, sulphuric acid, nitric acid, phosphoric acid, hydrochloric acid and sea water. Virgin grade resins and thick fluoropolymer linings provide for superior resistance to corrosive chemical effects, absorption and swelling.
