Ductile Iron Lugged & Tapped Butterfly Valve Stainless Steel Disc, PTFE Liner

This robust lugged and tapped butterfly valve is engineered for highflexibility installation and demanding fluid control applications. Built with a durable ductile iron body and a precision stainless steel disc, it features a PTFE liner for minimal friction and superior sealing performance. Its lugged and tapped end design allows the valve to be bolted into place between flanges, offering oneside removal or maintenance without disturbing adjacent piping.

Technical Data:

• Body Material: Epoxycoated ductile iron (high strength and corrosionresistant)
• End Connection Style: Lugged pattern with tapped bolt holes allows installation between flanges and supports oneside removal
• Disc Material: 316 stainless steel excellent wear and corrosion resistance
• Seat/Liner Material: PTFE (polytetrafluoroethylene) liner for ultrasmooth operation and reliable seal integrity
• Actuation Mounting: ISO5211 topmount pad for direct installation of lever or gearbox actuators
• Standards Compliance: Compliant with PED (Directive 97/23/EC) for pressure equipment
• Pressure Rating: PN16 nominal (~16bar) for sizes 812; for sizes 1½6 it's suited to PN10/16 flanges
• Temperature Range: 10°C to +120°C, aligned with PTFE liner performance
• Torque Requirement: Lowtorque design makes manual operation feasible and actuator sizing smaller
• Size Range: From 1½ up to 16 available; specific ratings may vary by size

Key Features:

• Lugged & tapped configuration enables easy retrofit or stepmaintenance: you can unbolt the downstream flange and remove the valve without impacting upstream lines.
• Stainless steel disc combined with PTFE liner gives long service life, smooth quarterturn operation and a tight shutoff even in difficult fluids.
• Low operation torque reduces actuator size or allows manual lever control for smaller sizes, improving value and installation flexibility.
• ISO5211 pad provides futureproof compatibility for automation without replacing the valve body.
• Ductile iron body offers mechanical strength and impact resistance, ideal for demanding plant environments, underground or exposed piping.

Applications:

• HVAC systems (chilledwater or condenser lines) where flow isolation and compact system maintenance are needed.
• Water treatment or distribution systems where oneside valve removal is advantageous.
• Process plants that require corrosionresistant control valves with low torque for manual or automatic operation.
• Any application where flangemounted butterfly valves are required for tight space fitting, ease of maintenance and longterm reliability.

In summary, this valve delivers a combination of structural strength, installation flexibility, smooth operation and futureautomation readiness, making it a strong choice for both current manual control and automated plant applications.
