DK67-WB Pneumatic Cast Iron Wafer Butterfly Valve - PTFE Sealed for Chemical Utility
The DK67-WB Pneumatic Wafer Butterfly Valve is a cost-effective, high-flow solution for automated isolation, particularly suited for applications requiring robust chemical resistance. It features a durable Cast Iron body for structural integrity at an economical price point. The critical feature is the PTFE (Polytetrafluoroethylene) seal/liner, which provides excellent resistance to aggressive chemicals, solvents, and high temperatures where standard elastomers fail. The wafer design is compact, and paired with a pneumatic actuator, the valve ensures rapid, quarter-turn on/off control for quick process cycling in chemical utility, petroleum, and industrial water treatment.
Features
A pneumatic cast iron wafer butterfly valve with highly chemical-resistant PTFE sealing, providing fast, cost-effective, and automated isolation for utility lines handling aggressive or high-temperature media.
✅Advanced PTFE Chemical Resistance: Equipped with a PTFE liner/seal, offering superior chemical inertness and temperature resistance, making it suitable for a wider range of corrosive media than standard rubber seals (like EPDM or NBR).
✅Cost-Effective Cast Iron Wafer Body: The Cast Iron construction provides high mechanical strength at an economical price, while the wafer (waist) design offers a compact, space-saving profile between flanges.
✅Rapid Pneumatic Automation: The pneumatic actuator ensures immediate, high-speed, quarter-turn operation, crucial for quick system isolation and efficient cycling in high-volume applications.
✅High Flow Capacity: The butterfly valve geometry allows for maximum fluid passage and minimal pressure drop, contributing to energy efficiency in bulk fluid transfer systems.
✅Tight Shutoff Capability: The resilient PTFE seating provides repeatable, reliable, bubble-tight shutoff, ensuring effective and complete process isolation.
