Fully lined PTFE electric butterfly valve
The Fully Lined PTFE Electric Butterfly Valve is a high-performance corrosion-resistant valve designed for automatic shut-off and flow regulation of highly corrosive fluids. The valve body and disc are fully lined with premium PTFE (Polytetrafluoroethylene) material, providing outstanding chemical resistance, excellent sealing performance, and long service life in aggressive operating environments.
Fully lined PTFE electric butterfly valve
Equipped with an electric actuator, this butterfly valve enables remote control, automatic operation, and precise flow adjustment, making it ideal for modern industrial automation systems. The full PTFE lining effectively isolates the metal components from the medium, preventing corrosion caused by acids, alkalis, solvents, and other chemical substances.
We provide professional OEM and ODM customization services, including customized valve sizes, pressure ratings, lining materials, flange standards, electric actuator brands, control signals, protection grades, wiring configurations, logo marking, and packaging solutions. Our engineering team can develop customized solutions according to customer drawings, technical requirements, and special working conditions.
Our fully lined PTFE electric butterfly valves are manufactured under strict quality management systems with complete valve industry certifications and inspection documents, including ISO quality certification, CE certification, material certificates, pressure testing reports, and other international valve industry certificates, ensuring reliable quality and global application compliance.
