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

This rugged, highperformance butterfly valve is designed for industrial-grade reliability and precision in demanding flow control environments. With a carbon steel body, stainless steel disc, and a reinforced PTFE (RPTFE) seat, it ensures long service life, excellent corrosion resistance, and dependable shut-off performance. Lever Operated 2" to 5", Gearbox Operated 6" to 12".

Technical Data:

• Body Material: Carbon steel (typically ASTM A216 WCB), offering robust strength and durability under high-pressure conditions
• Disc Material: Stainless steel (commonly CF8M), ensuring superior corrosion resistance and consistent operation
• Seat Material: RPTFE (Reinforced Polytetrafluoroethylene) ideal for low-friction sealing, wear resistance, and compatibility with a wide range of chemicals and temperatures
• Connection Type: Lugged body design compatible with PN16/25 2" to 4", PN16 5" to 12"
• Pressure Rating: PN25; provides flexibility for use in various pressure class systems
• Temperature Range: Operational range from approximately -60°C to +230°C, depending on the medium and system configuration
• Size Range: Typically available from DN50 (2") up to DN300 (12")
• Mounting Interface: ISO 5211 top pad for easy adaptation to gear operators or actuation systems
• Flow Geometry: Double-offset design reduces seat wear and operational torque, prolonging valve lifespan

Key Features:

• Durable Construction: Carbon steel body and stainless steel disc deliver exceptional resistance to mechanical stress and corrosion
• Superior Sealing: RPTFE seat ensures tight shut-off and reduced maintenance in high-cycle applications
• Lugged Design Advantage: Allows for removal of downstream piping without disturbing the upstream connection, facilitating maintenance and inspection
• Extended Temperature Range: Wide operating temperature tolerance supports use in cold storage, steam lines, and other thermally demanding environments
• Automation Ready: ISO top mount allows easy transition from manual to electric or pneumatic actuation
• Versatile Application: Compatible with liquids, gases, and mildly aggressive media in a variety of process and utility systems

Typical Applications:

• Water treatment and industrial process piping
• Steam and condensate systems (within seat limitations)
• Chemical and utility services
• Pumping stations and plantrooms
• High-cycle applications requiring durable valve performance with minimal downtime

Summary:

This high-performance lugged butterfly valve offers the strength of carbon steel, the corrosion resistance of stainless steel, and the low-maintenance efficiency of an RPTFE seat. It is a reliable and future-ready solution for critical flow control in high-demand industrial systems. Whether youre upgrading existing infrastructure or planning a new installation, this valve delivers performance where it counts.
