DELCO DK67-LB Pneumatic Lug Type Butterfly Valve – Cast Iron, End-of-Line Service

✅End-of-Line Capability: The threaded lug body allows the valve to be bolted to a single flange, serving as an end-of-line isolation point, a distinct advantage over standard Pneumatic Wafer Butterfly Valves.

✅Easy Downstream Maintenance: Enables the removal of downstream piping for repair or equipment replacement while maintaining full pressure on the upstream side, minimizing system downtime.

✅Robust Ductile Iron Body: Manufactured from high-strength Ductile Iron (GGG50) with epoxy coating, ensuring long-term structural integrity and rust resistance in municipal and industrial applications.

✅Bubble-Tight Sealing: Features a replaceable EPDM or NBR seat that provides a zero-leakage shutoff for water, air, and neutral gases, suitable for vacuum and pressure services.

✅Secure Installation: The full set of threaded lugs ensures precise alignment with the pipeline flange, preventing bolt relaxation and vibration issues common in high-flow lines.
