Pneumatic Control Flanged Butterfly Valve with Stainless Steel Construction

Introducing an exceptionally robust valve crafted for peak performance even in the most hostile environments. This corrosion-resistant marvel seamlessly combines turbine-driven efficiency with the unparalleled durability of a fluoropolymer lining, ensuring long-lasting, reliable operation amidst highly aggressive media.

Structural & Design Features
1. Turbine Drive System
- Featuring an advanced state-of-the-art worm gear mechanism, this turbine drive system provides minimal operating torque and ensures smooth, seamless operation. Whether managing large-diameter valves or frequent usage, it delivers impeccable control and unmatched reliability.
- Designed for versatile control, this valve is fully compatible with a wide array of actuators, including manual, electric, and pneumatic options, catering to diverse operational needs.

2. Fluoropolymer Lining & Corrosion Resistance
- The valve's robust body is fortified with high-performance fluoroplastics such as PTFE, FEP, and PFA, while the butterfly disc features a protective fluorine coating. This combination offers formidable resistance against a vast spectrum of corrosive agents including strong acids, alkalis, organic solvents, and oxidizers, effectively operating within a temperature range of **-50°C to 150°C**.
- By ingeniously integrating a liner-and-seat design, this valve isolates the media from metal components, ensuring unrivaled corrosion resistance and enhanced operational longevity.

3. Sealing Performance
- Employing a sophisticated four-stage sealing structure, this valve features a synergy of shaft transition curves, elastic O-rings, robust metal gaskets, and flexible seat grooves to deliver impeccable bidirectional zero-leakage sealing.
- Choose between a double eccentric or centerline design. Both options bolster sealing reliability by optimizing seal compression during closure, as evidenced in various model references.
