In industrial environments with strong acids and alkalis, valves act as "guardians" of pipeline systems, requiring resistance to media corrosion while ensuring fluid safety. PTFE-lined flanged butterfly valves achieve corrosion resistance, zero leakage, and reliable sealing through innovative design.

Five Key Highlights:

1. Centerline Structure for Reliable Sealing: The valve stem and disc are integrated, allowing for opening and closing with a 90° rotation of the disc, ensuring excellent sealing and zero leakage. The centerline sealing butterfly valve features a 360-degree concentricity between the disc and seat, providing bidirectional sealing capability.

2. Diverse Materials for Wide Adaptability: Valve bodies are available in gray cast iron, carbon steel, and stainless steel. Lining materials include PVDF, PCTFE, PTFE, FEP, and PFA, adaptable to various highly corrosive media.

3. Flexible Driving, Automatic and Efficient Operation: Supports manual, pneumatic, electric, and hydraulic actuation. It can be equipped with solenoid valves, positioners, or feedback devices for remote control, flow regulation, and automated operation.

4. Four-level sealing, leak-proof: Utilizing a four-level sealing structure, the sealing surface is lined with elastic gaskets. A groove and special rubber ring are fitted at the shaft end and the circumference of the disc to prevent media leakage, achieving long-term zero leakage.

5. Compact structure, easy installation: Small size, light weight, and compact structure facilitate installation and maintenance, suitable for various piping systems.
