      Yes. PTFE lining provides excellent resistance to sulfuric acid and many other strong acids. However, the exact concentration, operating temperature, and process conditions should be reviewed before valve selection.<\/p>\n\n\n\n

      What pressure ratings are available?<\/h3>\n\n\n\n

      PTFE lined flanged butterfly valves are commonly available in PN10, PN16, PN25, and ANSI Class 150 pressure ratings. Higher pressure designs may be available upon request.<\/p>\n\n\n\n

      What is the difference between PTFE and PFA lined butterfly valves?<\/h3>\n\n\n\n

      PTFE offers excellent chemical resistance and is widely used in corrosive applications. PFA provides similar chemical resistance but offers improved flexibility, higher purity, and better performance in certain high-temperature applications.<\/p>\n\n\n\n

      Can PTFE lined butterfly valves be automated?<\/h3>\n\n\n\n

      Yes. PTFE lined butterfly valves can be supplied with pneumatic actuators, electric actuators, limit switch boxes, positioners, and other automation accessories to meet process control requirements.<\/p>\n\n\n\n

      Which industries commonly use PTFE lined butterfly valves?<\/h3>\n\n\n\n

      These valves are widely used in chemical plants, pharmaceutical facilities, water treatment systems, chlor-alkali plants, pulp and paper mills, mining operations, and marine applications where corrosion resistance is required.<\/p>\n\n\n\n

      How do I choose the right PTFE lined butterfly valve?<\/h3>\n\n\n\n

      When selecting a PTFE lined butterfly valve, consider media type, chemical concentration, operating temperature, pressure rating, connection standard, valve size, and automation requirements. Consulting with an experienced valve manufacturer can help ensure optimal valve performance and service life.<\/p>","protected":false},"excerpt":{"rendered":"
