DK56-LB Electric Cast Iron Lug Butterfly Valve - Dead-End Service & Automated Isolation
The DK56-LB Electric Lug Butterfly Valve is a highly serviceable and cost-effective solution designed for automated flow isolation in utility, water, and HVAC pipelines. It features a durable Cast Iron body and a robust Lug pattern, which allows the valve to be securely bolted between pipeline flanges. Crucially, the Lug design supports dead-end service, meaning the valve can be fully isolated and removed from one side of the line for maintenance while the opposite side remains operational or pressurized, drastically simplifying and accelerating repair routines. Paired with the electric actuator, it provides fast, reliable automated control.
Features
An electric cast iron lug butterfly valve offering cost-effective, automated isolation and unique dead-end service capability for easy maintenance in general utility applications.
✅Lug Body Design for Dead-End Service: The threaded bolt holes on the valve perimeter allow it to be isolated and removed from one side of the flange connection without disturbing the piping or the flange on the opposite side, making it ideal for sections that require frequent maintenance.
✅Cost-Effective Cast Iron Construction: The Cast Iron body provides necessary mechanical strength and rigidity for low-to-medium pressure utility services (water, air, neutral liquids) at a significantly lower cost than steel alternatives.
✅Secure and Stable Installation: The Lug pattern ensures secure, independent bolting to both mating pipeline flanges, providing better stability and alignment during installation than standard wafer-style valves.
✅Reliable Electric Automation: Equipped with the electric actuator, the valve provides fast, quarter-turn, and reliable automated on/off switching, ensuring quick process isolation and control.
✅High Flow and Low Pressure Drop: The butterfly valve design offers excellent flow characteristics and minimal pressure drop, making it suitable for high-volume fluid transfer in municipal and industrial utility lines.
