Electric Lined Rubber Butterfly Valve (Electric Lined Anti-Corrosion Butterfly Valve) is an electric butterfly valve formed by vulcanizing rubber onto the valve body at high temperatures and integrating it with an electric actuator. Its rubber lining design effectively isolates the medium from metal contact, offering resistance to alkali salts and weak acids, making it suitable for corrosive media.
Depending on operating conditions, electric rubber-lined butterfly valves are categorized as fully lined or semi-lined to ensure sealing integrity and corrosion resistance across diverse environments. In media containing solid particles, rubber seals demonstrate superior wear resistance compared to PTFE seals.
