Stainless Steel HighPerformance Butterfly Valve Lugged PN16/25 Stainless Steel Disc RPTFE Seat

This stainless steel highperformance butterfly valve is designed for precision control and long-term durability in demanding industrial and process applications. Combining a stainless steel body and disc with a reinforced PTFE (RPTFE) seat, it offers exceptional resistance to corrosion, temperature, and pressure, making it ideal for harsh environments where reliability and clean operation are essential. Lever Operated 2" to 5", Gearbox Operated 6" to 12".

Technical Data:

• Body Material: Stainless steel (commonly CF8M or A351316 equivalent), ensuring excellent corrosion resistance, mechanical strength, and hygiene for aggressive or clean service applications
• Disc Material: Stainless steel, precisionmachined to maintain consistent sealing performance and smooth operation under varying flow conditions
• Seat Material: RPTFE (Reinforced Polytetrafluoroethylene) provides lowfriction sealing, enhanced chemical compatibility, and superior wear resistance, ensuring consistent tight shutoff performance even under pressure
• Connection Type: Lugged pattern body suitable for installation between PN16/25 2" to 4", PN16 5" to 12" flanges, allowing for secure alignment and easy maintenance access
• Pressure Rating: Dualrated for PN25 pressure systems; engineered to withstand highpressure flow and repeated operation cycles
• Temperature Range: Typical operating range from -60°C up to +230°C depending on process media and service conditions
• Size Range: Available in standard diameters from DN50 (2) up to DN300 (12), with larger options available for specific applications
• Mounting Interface: ISO5211 top flange provided for direct actuator or gearbox mounting, allowing future automation without valve replacement
• Flow Geometry: Doubleoffset disc design reduces seat friction during operation, minimising wear and extending service life

Key Features:

• Fully Stainless Construction: Ideal for environments where chemical, saline, or highmoisture exposure would compromise carbon steel components
• Enhanced Sealing: The RPTFE seat ensures a tight, leakfree seal and maintains its integrity through highcycle use and temperature fluctuations
• Compact Lugged Design: Provides secure bolting alignment and allows downstream pipeline removal without full system disassembly, ideal for maintenance or modular systems
• Smooth Flow Efficiency: Doubleoffset configuration ensures low torque operation, minimal flow resistance, and reduced seat wear
• AutomationReady: ISOstandard mounting interface supports manual, gearoperated, or actuated control systems
• Long Service Life: Built for durability with corrosionproof materials, reinforced seating, and precision manufacturing tolerances

Typical Applications:

• Chemical processing plants and industrial pipelines requiring corrosionresistant flow control
• Water treatment and desalination systems handling saline or treated water
• HVAC and thermal systems managing chilled or hot water circuits
• Food, beverage, and pharmaceutical facilities requiring clean, noncontaminating valve materials
• Marine, offshore, and environmental systems exposed to humidity, saltwater, or variable pressure conditions

Summary:

The Stainless Steel HighPerformance Lugged Butterfly Valve with an RPTFE seat combines strength, reliability, and adaptability in one compact design. Its stainless steel construction guarantees corrosion resistance and hygiene, while the RPTFE seat provides superior sealing and durability. Engineered for highpressure, highcycle, and highpurity applications, this valve is a premium choice for engineers who value performance, longevity, and futureproof automation compatibility.
