DELCO DK67-LB Pneumatic Lug Type Butterfly Valve - Cast Iron, End-of-Line Service
The DELCO DK67-LB features a Lug-style Ductile Iron body with threaded inserts, allowing it to be bolted directly to pipe flanges. This design enables end-of-line isolation and easy removal of downstream piping without draining the system. Powered by a reliable pneumatic actuator, it offers versatile automation for HVAC, water distribution, and fire protection systems.
Features
A versatile pneumatic lug-style butterfly valve capable of dead-end service, designed for easy downstream maintenance in water and HVAC pipelines.
✅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.
