DK67-LB-S Pneumatic Stainless Steel Lug Butterfly Valve - Fast Dead-End Service Isolation
The DK67-LB-S Pneumatic Lug Butterfly Valve is the superior choice for automated isolation in corrosive and sensitive industrial environments. Constructed from high-grade Stainless Steel (SS304/SS316), it offers exceptional chemical resistance. The key functional advantage is the Lug body design, which permits dead-end service—the valve can be safely removed and maintained from one side of the line while the opposite side remains pressurized or operational. Coupled with a pneumatic actuator, this valve delivers rapid, quarter-turn shutoff, minimizing maintenance time in chemical, food, and high-purity pipelines.
Features
A pneumatic stainless steel lug butterfly valve providing corrosion-resistant, high-speed automated isolation with dead-end service capability for easy maintenance in demanding industrial lines.
✅Corrosion Resistance (Stainless Steel): Manufactured from Stainless Steel (SS304/SS316), the valve is ideal for handling aggressive fluids, chemicals, and environments where Cast Iron would rapidly degrade.
✅Lug Design for Dead-End Service: The threaded lug holes allow the valve to be securely bolted to the pipeline and permit safe removal of the valve from one side for servicing without disturbing the opposite flange or emptying the entire line.
✅Rapid Pneumatic Automation: The pneumatic actuator provides immediate, high-speed, quarter-turn response, which is crucial for quick process isolation and efficient cycling in automated systems.
✅Secure and Stable Mounting: The Lug pattern ensures a secure, high-integrity connection, providing better stability and alignment than wafer types when installed between pipeline flanges.
✅Reliable Soft Sealing: Equipped with a resilient soft liner (e.g., EPDM, PTFE), the valve guarantees reliable, repeatable, bubble-tight shutoff for effective flow isolation.
