Overview:

The Pneumatic Wafer Butterfly Valve is an industrial valve designed for fast, automated control of fluid flow. Utilizing a pneumatic actuator, this valve is ideal for applications requiring rapid operation and consistent performance. Its wafer-style design allows easy installation between flanges, making it a space-saving and cost-effective solution.

Product Features:

  1. Wafer-Style Design:
    • Compact and Lightweight: The wafer design allows the valve to be installed between flanges, reducing weight and space requirements in the pipeline.
    • Flange Compatibility: Designed to fit between various flange standards (ANSI, DIN, JIS) without requiring extensive modifications.
  2. Pneumatic Actuation:
    • Quick Response: The pneumatic actuator enables rapid opening and closing of the valve, making it ideal for systems requiring fast response times.
    • Double-Acting or Spring-Return Options: Available in both double-acting (air-to-open, air-to-close) and spring-return (failsafe) configurations.
    • Air Supply: Operates with standard pneumatic air supply, typically 4-8 bar.
  3. Quarter-Turn Operation:
    • Fast Cycling: Requires only a 90-degree turn to fully open or close the valve, providing swift flow regulation.
    • High Cycle Life: Designed for durability and reliable performance, even in high-cycle applications.
  4. Resilient Sealing:
    • Soft Seals for Tight Shut-Off: Equipped with PTFE, EPDM, or NBR seals to ensure tight sealing and prevent leaks.
    • Corrosion-Resistant Options: Valve seats and discs are available in corrosion-resistant materials such as stainless steel for aggressive media.
  5. High Flow Capacity:
    • Minimal Pressure Drop: The streamlined disc design reduces turbulence, resulting in smooth fluid flow and low pressure loss.
    • Bidirectional Flow: Allows flow in either direction, providing operational flexibility in piping systems.
  6. Durable Construction:
    • Robust Body Materials: Constructed from materials like ductile iron, carbon steel, or stainless steel to ensure strength and long service life.
    • Corrosion Resistance: Available with special linings or coatings for resistance to corrosive fluids in chemical and wastewater applications.
  7. Wide Range of Sizes and Pressure Ratings:
    • Size Range: Available in sizes from DN40 to DN1200, covering a wide range of industrial applications.
    • Pressure Ratings: Typically rated for PN10 to PN16, with options available for higher pressures based on specific application needs.
  8. Temperature Range:
    • Versatile Temperature Handling: Depending on the materials used, the valve can handle temperatures from -20°C to 200°C.
  9. Low Maintenance:
    • Simple Design: The pneumatic actuator requires minimal maintenance compared to more complex systems, making it cost-effective for long-term use.

Applications:

  • Water Treatment Plants: For controlling water flow in treatment processes, filtration systems, and reservoirs.
  • HVAC Systems: Used in heating, ventilation, and air conditioning systems to regulate air or fluid flow.
  • Chemical Processing: Ideal for controlling the flow of corrosive chemicals when equipped with appropriate seal and body materials.
  • Oil and Gas Pipelines: Provides reliable operation in pipelines transporting hydrocarbons and other gases or liquids.
  • Food and Beverage Industry: Suitable for sanitary applications when constructed from stainless steel with food-grade seals.
  • Power Generation: Utilized for controlling steam or water in power plants and energy systems.

Advantages:

  • Rapid Operation: Pneumatic actuation ensures quick and precise valve control, improving overall system efficiency.
  • Compact and Lightweight: The wafer design saves space and reduces weight, making installation easier.
  • High Flow Efficiency: The low resistance of the butterfly disc allows for efficient fluid flow with minimal pressure drop.
  • Reliable Sealing: Provides a tight shut-off to prevent leaks, even in demanding industrial environments.
  • Cost-Effective Automation: Pneumatic actuation offers an affordable automation solution compared to electric actuators, especially in systems requiring frequent cycling.

Conclusion:

The Pneumatic Wafer Butterfly Valve is an excellent choice for industries requiring reliable, fast, and cost-effective flow control. Its pneumatic actuation allows for swift operation, while the compact wafer design makes it suitable for tight spaces. With its high flow capacity, durable construction, and versatile application range, this valve is ideal for use in water treatment, HVAC systems, chemical processing, and beyond.
