Product Description

The F46 fluorine-lined butterfly valve is a specialized type of valve where the internal surfaces are lined with F46, which is a grade of fluoroplastic (PFA or FEP). F46 is known for its excellent chemical resistance, thermal stability, and non-stick properties, making it highly effective in handling corrosive fluids.
 

Advantages of F46 Fluorine-Lined Valves:

• Superior corrosion resistance: They handle highly corrosive fluids that would damage most metals and other materials.
• High temperature and pressure tolerance: Ensures longevity and reliability in extreme environments.
• Non-stick surface: Prevents buildup and ensures easy cleaning and maintenance.

• Material Lining:

  • F46 (PFA/FEP): The valve is lined with F46, which is a type of fluoropolymer (often PFA or FEP). This material offers outstanding resistance to chemical corrosion, high temperatures, and abrasion.

• Chemical Resistance:

  • F46 fluoroplastics can handle a wide range of aggressive chemicals, including acids, alkalis, solvents, and various gases, making these valves ideal for harsh industrial applications.

• Butterfly Design:

  • The valve operates by rotating a disc (butterfly) on a central shaft, which regulates the flow of liquids or gases. The valve's design provides quick shut-off and control.

• Non-Stick Properties:

  • F46 has a very low coefficient of friction and non-stick properties, reducing the likelihood of material buildup or clogging, even with sticky or viscous fluids.

• Temperature Range:

  • F46 is known for its thermal stability, capable of withstanding both very low and very high temperatures (ranging from -200°C to +250°C), depending on the exact material composition.

The stainelss steel butterfly valve regulates flow by rotating the disc within the flow path. When the valve is fully open, the disc is positioned parallel to the flow direction, allowing fluid to pass through with minimal obstruction. Conversely, when the valve is closed, the disc is rotated perpendicular to the flow, blocking the passage of fluid.

Butterfly valves are commonly applicating in a variety of industries, including:

1. Oil and Gas: Triple offset butterfly valves applicate in the oil and gas industry. For pipeline isolation, compressor stations, and refining processes.
2. Chemical: Triple offset butterfly valves are popular in chemical plants for applications. Such as corrosive and abrasive fluid handling, high-temperature services, and toxic gas handling.
3. Power Generation: Triple offset butterfly valves play an important role in power generation. For applications such as steam isolation, turbine bypass, and cooling water control.
