Lugged & Tapped Butterfly Valve Stainless Steel Disc, FKM (Viton®) Liner

This premium lugged and tapped butterfly valve is designed for highperformance service where flexibility, durability and superior sealing are essential. Featuring a stainless steel disc, a highresistance FKM (Viton®) liner and a lugged body with tapped holes, the valve offers maintenancefriendly installation, rugged service and long life in challenging plant environments.

Technical Data:

• Body Material: Ductile iron or epoxycoated iron cast, lugged pattern with tapped bolt holes for flange mounting on one side.
• Disc Material: 316 stainless steel offers maximum corrosion resistance and durability for aggressive fluids or demanding applications.
• Liner / Seat: FKM (fluoroelastomer, Viton®) liner excellent resistance to oils, solvents, high temperatures and aggressive media, with a temperature range typically from -10°C up to +140°C
• End Connection Style: Lugged pattern with tapped holes, allowing the valve to be installed between flanges and enabling removal of downstream pipeline without disturbing upstream side. 1½ to 6 to fit PN10/16 Flanges. 8 to 24 to fit PN16 Flanges
• Torque Rating: Designed for lowtorque operation thanks to frictionoptimised liner/disc interface, reducing actuator size or easing manual lever operation.
• Mounting Pad: ISO5211 top mounting pad included for direct actuation or manual lever installation.
• Pressure Rating: Rated PN16 1½ to 12, PN10 14 to 24
• Flow Path: Fullbore disc design ensures minimal pressure drop and effective shutoff.
• Sizes Available: Generally from 1 1/2 up to 12
• Installation Orientation: Bidirectional flow capable (check size and liner spec); suitable for both manual and actuated operation.

Key Features:

• Lugged & tapped configuration allows oneside flange removal for maintenance or replacement without full pipeline shutdown.
• Stainless steel disc + FKM liner provides outstanding resistance to corrosion, chemicals and elevated temperatures, while delivering tight sealing and smooth operation.
• Lowtorque design reduces actuator sizing or allows manual lever operation in many applications, cutting cost and complexity.
• ISO5211 mounting pad ensures seamless transition from manual control to pneumatic or electric actuation in the future.
• Durable body construction carries structural strength for plant room, water treatment, HVAC, chemical or utility applications.

Typical Applications:

• Chemical feed lines, solvent or oilbased systems where FKM liners are required.
• HVAC chilled or hotwater circuits where robust, easily serviced isolation is needed.
• Pipeline installations where space is tight or future automation is planned.
• Process systems needing oneside maintenance access without full pipeline breakout.

In short, this lugged and tapped butterfly valve with stainless steel disc and FKM liner is a flexible, highquality choice for demanding installations. It combines easy maintenance, strong materials and forwardlooking automation readiness, making it a smart investment for todays systems and tomorrows upgrades.
