API 609 ASME CE DN200 PN10 GGG40 Ductile Iron 2507 Duplex Steel PTFE Full-Lined Wafer Type Concentric Line Soft Seal Butterfly Valve
TIANYU’s PTFE-lined concentric line butterfly valve delivers cost-effective, leak-tight control for corrosive media. Customize it to your operational needs: opt for PFA lining (up to 200℃) for heated fluids, 2205 duplex steel for extreme saline service, or PN25 pressure rating for higher-pressure systems. Add pneumatic/electric actuators for automated control, or FDA-compliant lining for food/pharmaceutical use. These tweaks enhance compatibility with your specific media, pressure, and workflow—boosting reliability, reducing long-term costs, and ensuring seamless integration into your process.
