Carbon Steel High Performance Butterfly Valve Wafer Type Stainless Steel Disc RPTFE Seat (LV955)

Engineered for demanding flow control environments, this high-performance wafer-pattern butterfly valve features a rugged carbon steel body, corrosion-resistant stainless steel disc, and a reinforced PTFE (RPTFE) seat. Its compact design and versatile compatibility make it ideal for tight installation spaces without compromising durability or sealing efficiency.

Technical Data:

• Body Material: High-grade carbon steel (typically ASTM A216 WCB or equivalent), offering excellent mechanical strength and resistance to pressure-related stresses
• Disc Material: Stainless steel (commonly CF8M or equivalent), ensuring corrosion resistance and smooth, reliable operation in aggressive media
• Seat Material: RPTFE (Reinforced Polytetrafluoroethylene), known for its chemical resistance, dimensional stability under load, and broad temperature tolerance
• Connection Type: Wafer-style body designed for installation between flange pairs; compatible with PN10/16/25 & ANSI 150 Flanges 2" to 10", PN10/16 & ANSI 150 Flanges 12"
• Pressure Rating: PN25
• Temperature Range: Typically rated for service from -20°C to +230°C, depending on media and installation conditions
• Size Range: Available across a wide spectrum of nominal bore sizes, from DN50 (2") and upwards
• Mounting Interface: ISO 5211 top flange allows for direct mounting of manual gear operators or automation devices

Key Features:

• High Strength Construction: Carbon steel body provides long-lasting durability in industrial and utility environments
• Superior Sealing: RPTFE seat resists deformation under pressure and maintains tight sealing across a range of temperatures and flow conditions
• Corrosion-Resistant Internals: Stainless steel disc resists wear and maintains structural integrity even in corrosive or chemically reactive environments
• Compact Wafer Design: Ideal for space-conscious installations, with simple integration between existing flanges
• Automation Ready: ISO mounting makes this valve future-proofstart with manual control and easily switch to electric or pneumatic actuation later
• Low Pressure Drop: Full-bore or near full-bore flow path helps maintain system efficiency with minimal turbulence

Typical Applications:

• Chemical processing lines handling aggressive or high-purity media
• HVAC systems requiring reliable flow control of steam, chilled water, or condensate
• Power generation and water utility systems where high durability and tight shut-off are essential
• Food and beverage processing plants that require corrosion resistance and low-maintenance operation
• Industrial systems requiring upgrade-ready valves capable of transitioning to automated control

Summary:

This high-performance butterfly valve is built for engineers and plant managers who demand more than just standard shut-off capability. With a carbon steel body, stainless steel disc, and reinforced PTFE seat, it combines chemical resistance, high pressure tolerance, and operational versatility. Whether you're upgrading an existing system or planning a new installation, this valve offers exceptional reliability and adaptability for your fluid control needs.
