DK55-CF Electric Cast Steel Fluorine-Lined Flange Ball Valve - High Strength & Extreme Corrosion Resistance
The DK55-CF Electric Fluorine-Lined Ball Valve is engineered for the toughest corrosive services, where mechanical strength and chemical immunity are both essential. It features a robust Cast Steel body (providing superior mechanical strength and pressure resistance) fully protected by an internal, chemically inert Fluorine Lining (e.g., PTFE/FEP/PFA). This unique combination ensures extreme chemical stability against concentrated acids, strong alkalis, and aggressive solvents. Paired with the electric actuator, this flanged valve delivers safe, automated, on/off control in high-pressure, high-temperature chemical pipelines.
Features
An automated electric ball valve combining the high mechanical strength of a cast steel body with a chemically inert fluorine lining for zero-leakage control of highly corrosive fluids under high pressure and temperature.
✅Integrated Strength and Immunity: The Cast Steel body provides the necessary mechanical integrity and pressure containment, while the full fluorine lining ensures that no process media touches the metal, achieving the highest level of corrosion resistance.
✅Extreme Chemical Resistance: The high-grade fluorine lining (such as FEP or PFA) offers near-universal chemical compatibility, making the valve suitable for handling highly corrosive media, including concentrated hydrochloric acid, sulfuric acid, and various strong solvents.
✅Secure Flanged Connection: Designed with standard flanged connections, providing a robust, reliable, and secure seal for critical pipelines operating under high pressure and potential thermal stress.
✅Reliable Electric Automation : Equipped with the actuator, the valve allows for safe, remote on/off control, essential for handling hazardous and aggressive fluids and ensuring quick process isolation.
✅Bubble-Tight Sealing: The resilient sealing properties of the fluorine lining ensure repeated, bubble-tight shutoff, minimizing the risk of internal or external leakage of dangerous and costly process media.
