Hastelloy Lined PTFE Butterfly Valve DN80 Price for Strong Acid & Strong Alkali Working Conditions
Advantages of Hastelloy Lined PTFE Butterfly Valve
Hastelloy itself offers outstanding corrosion resistance, and the PTFE lining process further enhances the valve's performance against strong acids (e.g., sulfuric acid, hydrochloric acid) and strong alkalis (e.g., sodium hydroxide). F46 or PFA lining effectively isolates the medium from the metal valve body, preventing corrosion and leakage, and providing a much longer service life than standard stainless steel valves.The main Butterfly Valve product names of China Butterfly Valve Network include:Flange Soft-sealed Butterfly Valve,Flange Ceramic Hard-sealed Butterfly Valve,High Temperature Butterfly Valve,Lug Butterfly Valve,Three Eccentric Multi-level Metal Hard-sealed Wafer Butterfly Valve,Tipping Sealing Butterfly Valve,Sanitary Butterfly Valve,Threaded Connection Butterfly Valve.
