DK56-DC Electric Cast Iron Fluorine-Lined Wafer Butterfly Valve - Compact Corrosion Control
The DK56-DC Electric Wafer Butterfly Valve is a highly cost-effective and compact solution for automated control of corrosive fluids. It features a durable Cast Iron body combined with a protective, internal Fluorine Lining (e.g., PTFE or FEP), offering excellent chemical immunity against acids and alkalis. The wafer (lugless) design fits securely between pipeline flanges, minimizing face-to-face dimensions and installation weight. Paired with the electric actuator, this valve is ideal for high-volume, low-to-medium pressure corrosive applications like wastewater treatment, chemical transfer, and plating lines.
Features
A compact, cost-effective electric wafer butterfly valve featuring a cast iron body and fluorine lining for reliable, automated on/off control of corrosive media where space is limited.
✅High Chemical Immunity (Fluorine Lining): The resilient fluorine lining (PTFE/FEP) fully isolates the cast iron body from the process fluid, providing superior protection against strong acids, concentrated alkalis, and aggressive chemical solutions.
✅Space-Saving Wafer Design: The wafer (also known as against-clamp) structure is extremely lightweight and compact, requiring minimal face-to-face space for installation, which is a major advantage in tightly packed industrial environments.
✅Cost-Effective Durability (Cast Iron): The Cast Iron body provides necessary mechanical strength and rigidity at a significantly lower material cost compared to high-grade steel alloys, offering excellent value for budget-conscious projects.
✅Reliable Electric Automation: Equipped with the electric actuator, the valve ensures fast, quarter-turn, and reliable automated on/off service, essential for high-volume fluid switching.
✅Excellent Flow Characteristics: As a butterfly valve, the design inherently provides high flow capacity and a low pressure drop, making it suitable for high-volume fluid transfer and bulk handling of corrosive media.
