Ductile Iron Lug Type Butterfly Valve

Ductile Iron Lug Type Butterfly Valve Description

Ductile iron lug type butterfly valves provide efficient on/off flow control in industrial piping systems. Constructed with a rugged ductile iron body and disc, these valves deliver the strength and durability needed for years of reliable service. The compact wafer-style design features lug end connections for easy installation between pipe flanges, making them ideal for applications with space restrictions. EPDM seating provides a tight seal, with the disc rotating 90 degrees for precise flow control. Available in a range of sizes from 2" to 48" and pressure classes up to 285 psi, our ductile iron lug butterfly valves can meet the most demanding needs. With proper installation and maintenance, these heavyweight valves offer outstanding performance and long operational life. Trust in superior quality ductile iron lug type butterfly valves for your toughest flow control challenges.Contact us today for more information or to order high-quality ductile iron lug type butterfly valves.

Ductile Iron Lug Type Butterfly Valve Advantages:

     •  Durable Construction - The ductile iron body and disc provide excellent strength and corrosion resistance for long service life.

     •  Tight Shutoff - The EPDM seat provides positive bi-directional shutoff when the disc is at 90 degrees. This prevents leakage.

     •  Easy Maintenance - The disc can be easily replaced without removing the valve from the pipeline if needed.

     •  Compact Design - The lug wafer style allows installation in tight spaces without disrupting pipelines.

     •  Flow Control - The disc can throttle flow when partially open, allowing precise regulation.

     •  High Pressure Rating - Available in pressure classes up to 285 psi to suit many industrial applications.

     •  Low Torque - The smooth disc operation allows easy actuation even in large sizes.

     •  Cost Effective - Ductile iron lug valves offer an economical solution compared to other valve designs.

     •  Versatile - Suitable for a wide range of media including water, chemicals, oil, and gases.

     • Reliable Shutoff - The metal seat provides positive shutoff and good abrasion resistance.
