DK67-FB Pneumatic Cast Iron Flanged Butterfly Valve - High Stability & Fast Isolation
The DK67-FB Pneumatic Flanged Butterfly Valve is built for reliable, automated flow isolation in large-diameter pipelines, offering superior stability compared to wafer designs. Constructed from durable Cast Iron, it provides necessary mechanical strength at an economical price. The flanged connection ensures a secure, high-integrity mounting interface, critical for high-pressure or high-volume utility, water, and HVAC systems. Coupled with a pneumatic actuator, this valve delivers rapid, quarter-turn on/off control for efficient process cycling and quick emergency shutoff.
Features
A robust pneumatic cast iron flanged butterfly valve, designed for secure, stable mounting and fast, reliable automated on/off control in high-volume industrial and utility applications.
✅High Stability Flanged Connection: Features secure flanged ends, providing a rigid, high-integrity connection to the pipeline that is vital for stability and alignment in high-volume and large-bore applications.
✅Cost-Effective Cast Iron Construction: The Cast Iron body provides necessary durability and mechanical strength for general industrial service (water, air, neutral liquids) at an advantageous cost.
✅Rapid Pneumatic Automation: The pneumatic actuator ensures immediate, high-speed, quarter-turn response, ideal for quick system isolation and efficient high-frequency cycling.
✅Excellent Flow Characteristics: The butterfly valve design provides high flow capacity and a low pressure drop, optimizing the energy efficiency of bulk fluid transfer systems.
✅Versatile Soft Sealing: Typically equipped with a resilient soft liner (e.g., EPDM or NBR), offering reliable bubble-tight shutoff performance for low-to-medium pressure applications.
