Fully lined PTFE pneumatic butterfly valve
The Fully Lined PTFE Pneumatic Butterfly Valve is a high-performance corrosion-resistant valve designed for automatic shut-off and flow control of highly corrosive media. The valve body and internal wetted parts are fully lined with premium PTFE (Polytetrafluoroethylene) material, providing excellent chemical resistance, superior sealing performance, and extended service life in aggressive industrial environments.
Fully lined PTFE pneumatic butterfly valve
Driven by a pneumatic actuator, this butterfly valve offers fast operation, reliable automation, and stable control performance. The complete PTFE lining creates a protective barrier between the valve body and the medium, effectively preventing corrosion caused by strong acids, alkalis, solvents, and other chemical fluids.
The valve features a compact structure, low operating torque, quick response, and excellent shut-off capability. It is widely used in automated process systems where corrosion resistance and reliable remote operation are required.
We provide professional OEM and ODM customization services, including customized valve dimensions, lining materials, pressure ratings, flange standards, pneumatic actuator specifications, control accessories, surface treatments, logo branding, and packaging solutions. Our engineering team can manufacture valves according to customer drawings, technical requirements, and special operating conditions.
Our fully lined PTFE pneumatic butterfly valves are produced under strict quality control systems with complete valve industry certifications and inspection documents, including ISO quality certification, CE certification, material certificates, pressure testing reports, and other internationally recognized valve industry certificates, ensuring dependable performance and compliance with global standards.
