Overview:

The Large-Diameter Flanged Butterfly Valve is designed for high-capacity flow control in industrial and municipal systems. Its robust construction and wide range of sizes make it ideal for large pipelines, providing reliable performance in demanding applications such as water distribution, wastewater treatment, and oil and gas transport.

Product Features:

  1. Large-Diameter Capability:
    • Wide Range of Sizes: Available in sizes from DN300 to DN3000, making it suitable for large-scale applications that require high flow rates.
    • Efficient Flow Control: The large disc design ensures smooth and precise regulation of fluid flow with minimal pressure loss.
  2. Flanged Connection:
    • Secure and Leak-Free Installation: The flanged connection ensures a tight seal and is compatible with various piping systems (ANSI, DIN, JIS standards).
    • Easy Maintenance: Flanged ends make installation and maintenance convenient, even for large-sized valves.
  3. Durable Construction:
    • Rugged Materials: Made from high-grade materials such as ductile iron, carbon steel, or stainless steel, ensuring durability and resistance to corrosion, abrasion, and high-pressure environments.
    • Coating Options: Optional corrosion-resistant coatings (e.g., epoxy, PTFE) for enhanced durability in aggressive environments.
  4. Sealing Options:
    • Soft and Hard Seals: Available with soft sealing materials like EPDM, NBR, or PTFE for tight shutoff, or metal-to-metal sealing for high-temperature or high-pressure applications.
    • Bubble-Tight Shutoff: Ensures zero leakage in both low and high-pressure systems, providing excellent sealing performance.
  5. Low Torque and Easy Operation:
    • Manual, Electric, or Pneumatic Actuation: Compatible with a variety of actuation methods, making it easy to operate in both manual and automated systems.
    • Low Torque Requirement: Designed to reduce the torque needed for opening and closing, making it energy-efficient and reducing operational costs.

Applications:

  • Water Distribution and Treatment: Ideal for controlling large volumes of water in municipal systems.
  • Oil and Gas Industry: Suitable for pipelines carrying crude oil, natural gas, or other petroleum products.
  • HVAC Systems: Used in large commercial or industrial heating, ventilation, and air conditioning systems.
  • Power Generation: Suitable for cooling water, steam, or other fluids in power plants.

The Large-Diameter Flanged Butterfly Valve is built to handle high-flow, high-pressure applications with minimal maintenance, making it a cost-effective and reliable solution for large-scale industrial systems.
