DELCO DK56-DC Electric Fluorine Lined Wafer Butterfly Valve for Universal Chemical Resistance

✅ Universal Corrosion Resistance: The core benefit is the valve’s comprehensive fluorine lining (PTFE) on the body and disc. This lining isolates the base metal (Cast Iron, WCB, or Stainless Steel) from the medium, making the valve chemically inert and suitable for handling nearly all known corrosive liquids, including concentrated mineral acids and powerful oxidizers.

✅ Wide Temperature Adaptability: The PTFE lining provides high thermal stability, allowing the valve to operate reliably across a broad temperature range, which is essential in chemical and pharmaceutical processing where temperatures frequently fluctuate.

✅ Electric Actuation for Automation: Equipped with a dedicated electric actuator, the valve supports both simple ON-OFF switch control and precise Regulation Type (modulating) control, facilitating seamless integration into automated control systems (DCS/PLC).

✅ Versatile Design and High-Pressure Rating: Built with a space-saving Wafer or Flanged connection design, the valve fits easily between pipe flanges. It maintains structural integrity with Nominal Pressure ratings of 1.0 MPa and 1.6 MPa(150LB equivalent), ensuring safety in medium-pressure processes.

✅ Superior Service Life: By protecting the metal body with a robust PTFE liner, the valve’s service life is dramatically extended, offering a cost-effective and low-maintenance alternative to solid alloy valves in highly corrosive applications.
