Overview:

The Electric Wafer Butterfly Valve is a highly efficient, automated valve designed for regulating and isolating flow in various industrial applications. Its wafer-type design makes it compact, lightweight, and easy to install between flanges, while the electric actuator allows for precise and automated control of fluid flow.

Product Features:

  1. Compact Wafer Design:
    • Space-Saving: The wafer design allows the valve to be installed between flanges, which reduces the overall space and weight of the system.
    • Flange Compatibility: It can be used with different flange standards (ANSI, DIN, JIS) and does not require additional gaskets for sealing.
  2. Electric Actuation:
    • Automated Control: The valve is equipped with an electric actuator that enables remote and automatic operation, eliminating the need for manual intervention.
    • Precision Control: Provides accurate control over the valve position, ensuring precise regulation of fluid flow.
    • Wide Input Options: Operates using standard electrical inputs, including 220V AC, 24V DC, or customized control signals (such as 4-20mA for modulating control).
  3. Quarter-Turn Operation:
    • Fast Response: The valve’s design allows it to fully open or close with a 90-degree turn, providing rapid and efficient control of fluid flow.
    • Failsafe Options: Available with failsafe mechanisms (spring return or battery backup) to ensure that the valve returns to a pre-set position during power failures.
  4. Versatile Sealing Materials:
    • Resilient Sealing: Equipped with soft seals such as PTFE, EPDM, or NBR for excellent leak-tight performance and durability.
    • Corrosion-Resistant Options: Valve seats and discs are available in a variety of materials, including stainless steel and ductile iron, to handle corrosive or abrasive media.
  5. Leak-Tight Shut-Off:
    • Designed to ensure minimal leakage when the valve is in the closed position, providing reliable shut-off in various pipeline systems.
  6. High Flow Capacity:
    • Minimal Pressure Drop: The streamlined disc design minimizes turbulence and pressure loss, ensuring smooth and efficient flow through the valve.
    • Bidirectional Flow: The valve allows for control of flow in both directions, providing operational flexibility.
  7. Wide Range of Sizes and Pressure Ratings:
    • Available in sizes from DN40 to DN1200, making it suitable for small to large-scale industrial systems.
    • Pressure Ratings: Typically rated for PN10 to PN16, with the ability to handle varying pressure requirements based on the valve size and materials used.
  8. Temperature Resistance:
    • Suitable for a wide range of temperatures, depending on the sealing and body materials, typically ranging from -29°C to 180°C.
  9. Durable Construction:
    • Body Materials: The valve body is constructed from durable materials such as stainless steel, carbon steel, or ductile iron to ensure long-lasting performance, even in harsh environments.
    • Corrosion Resistance: Available with special coatings or corrosion-resistant materials to withstand aggressive media in chemical or water treatment applications.

Applications:

  • Water Treatment: Ideal for controlling water flow in treatment plants, cooling towers, and desalination systems.
  • HVAC Systems: Frequently used in heating, ventilation, and air conditioning systems to regulate air or fluid flow.
  • Food and Beverage Industry: Suitable for sanitary applications with the use of stainless steel components.
  • Chemical Processing: Compatible with corrosive chemicals when equipped with appropriate lining and seal materials.
  • Power Generation: Used for controlling water and steam flow in power plants.
  • Oil and Gas: Suitable for managing the flow of oil, gas, and other hydrocarbons in pipelines.

Advantages:

  • Automated Control: Provides seamless integration into automated systems, allowing for remote operation and monitoring.
  • Energy Efficient: The electric actuator provides efficient valve operation, reducing the need for manual labor and improving overall system performance.
  • Compact and Lightweight: The wafer-style design offers a space-saving solution for tight installations.
  • High Flow Capacity: Ensures minimal pressure drop while providing efficient flow control.
  • Low Maintenance: Electric actuation reduces wear and tear compared to manual or pneumatic systems, leading to lower maintenance costs.

Conclusion:

The Electric Wafer Butterfly Valve is an ideal solution for applications requiring automated, reliable, and precise flow control. Its compact design, fast operation, and versatility in handling different media make it a preferred choice for industries such as water treatment, HVAC, and chemical processing. With the added benefit of remote operation and high sealing performance, this valve offers an efficient and cost-effective solution for modern industrial systems.
