Stainless Steel High Performance Butterfly Valve Wafer Type Stainless Steel Disc RPTFE Seat

This high-performance wafer-type butterfly valve is engineered for critical flow control applications where strength, corrosion resistance, and long-term reliability are non-negotiable. Featuring a robust stainless steel body and disc combined with a reinforced PTFE (RPTFE) seat, it ensures precise shut-off, exceptional durability, and compatibility with a wide range of industrial media. Lever Operated 2" to 5", Gearbox Operated 6" to 12".

Technical Data:

• Body Material: High-grade stainless steel (typically CF8M or A351-316 equivalent), offering outstanding corrosion resistance and mechanical strength
• Disc Material: Stainless steel, matched with the body for thermal compatibility and superior performance under demanding conditions
• Seat Material: RPTFE (Reinforced Polytetrafluoroethylene), offering enhanced strength, improved wear resistance, and broader chemical compatibility compared to standard PTFE
• Connection Type: Wafer-style body fits securely between standard flange pairs, simplifying installation and saving space. PN10/16/25 & ANSI 150 Flanges 2" to 10", PN10/16 & ANSI 150 Flanges 12"
• Pressure Rating: PN25
• Temperature Range: Typically operates within -60°C to +230°C, depending on the medium and seat configuration
• Size Range: Commonly available from DN50 (2") and up, suitable for medium to large-scale systems
• Actuation Compatibility: ISO 5211 top flange allows direct mounting of manual gearboxes, electric actuators, or pneumatic operators

Key Features:

• Corrosion-Resistant Construction: Stainless steel body and disc provide exceptional protection in aggressive environments
• Enhanced Sealing: RPTFE seat ensures tight shut-off under fluctuating pressure and temperature conditions, with low deformation
• Compact Design: Wafer body allows for installation in limited spaces without sacrificing performance
• Automation Ready: Standardised ISO mounting pad enables simple upgrade to automated actuation
• High-Flow Efficiency: Full or near-full bore design minimises pressure drop and supports efficient fluid handling

Typical Applications:

• Chemical processing systems handling corrosive or reactive media
• Power generation and utility pipelines requiring high-cycle reliability
• Steam and condensate systems within specified seat limits
• Pharmaceutical, food, and beverage production lines needing sanitary, low-maintenance valves
• Retrofit and upgrade projects where space and performance are critical

Summary:

Built for environments that demand more from their valve infrastructure, this stainless steel high-performance butterfly valve delivers precision, strength, and reliability. Whether installed for manual operation or prepared for future automation, it stands as a durable and efficient solution for high-demand fluid control systems.
