INFLAS® Butterfly Valve

The INFLAS® Butterfly Valve: A Breakthrough in Abrasion-Resistant and Sensitive Media Handling

Ebro Armaturen’s INFLAS® butterfly valve represents cutting-edge innovation in sealing technology, offering a reliable and efficient solution for managing highly abrasive or sensitive media. Engineered with an inflatable seat system, this valve is tailored for applications where traditional sealing mechanisms fall short due to excessive wear or sensitivity to grinding and clamping forces. From bulk goods handling to pneumatic conveying systems, the INFLAS® valve stands out for its exceptional performance, versatility, and safety.

Revolutionary Inflatable Seat Technology

The INFLAS® sealing system operates on a unique inflatable seat mechanism that provides exceptional sealing performance while significantly reducing wear. In the closed position, low air pressure inflates the liner, pressing it securely against the disc. This ensures a tight seal, even with challenging media such as powders, granulates, or abrasive substances.

When the valve needs to open, the air pressure is released, creating a small air gap between the liner and the disc. This innovative design minimizes friction and torque, making it easier to operate the valve and significantly extending the lifespan of its components. By reducing the grinding or clamping of sensitive materials between the disc and liner, the INFLAS® valve offers a gentle handling solution for fragile substances in applications like the food industry or weighing technology.

For more demanding environments involving high pressures, pressure surges, or extremely abrasive materials, the INFLAS® system also offers a gap-free (GF) version. This special design ensures a higher degree of protection and reliability, making it ideal for core shooting machinery or other heavy-duty applications.

The INFLAS® butterfly valve delivers a range of advantages that set it apart from conventional valve designs:

  • Minimal Wear: Thanks to the inflatable seat, the valve components experience very low wear, even when handling abrasive media. This results in longer service life and reduced maintenance requirements.
  • Lower Operating Torque: The air gap created during the opening process drastically reduces the torque needed, enabling the use of smaller actuators, which in turn lowers operational costs.
  • Gentle Media Handling: The unique design prevents grinding or clamping of sensitive media, ensuring that fragile materials maintain their integrity throughout the process.
  • Enhanced Safety: The valve features a cascade shaft seal that provides additional safety by preventing the ingress of false air and simultaneously shielding the shaft bearings from dirt and dust.

The INFLAS® valve is designed to seamlessly integrate into automated systems, ensuring precise and reliable operation. The EBRO control system offers a step-by-step process for managing the valve’s functionality:

  • Upon receiving a digital “OPEN” signal, air pressure behind the liner is released.
  • Once the liner is deflated, the valve opens, confirmed by the “OPEN” position signal.
  • When the signal disappears, the valve closes, and the liner is pressurized again to ensure a secure seal.
  • A plausibility check verifies that the liner is correctly pressurized, reporting an “OK” signal to confirm operational safety.

The INFLAS® butterfly valve is highly versatile, serving a wide array of industries and applications:

  • Bulk Goods Handling: Ideal for managing abrasive or fragile solid materials in industries like mining and material processing.
  • Food Industry: Gentle sealing ensures the integrity of sensitive food products while maintaining high hygiene standards.
  • Pneumatic Conveying Systems: The reduced torque and reliable sealing make it a perfect choice for systems transporting powders, granulates, or other bulk materials.
  • Weighing Technology: Its precision and gentle operation ensure accurate material handling in sensitive weighing systems.
  • Core Shooting Machinery: The GF version offers superior resistance to higher pressures and abrasive media, making it indispensable in specialized industrial applications.

The INFLAS® valve is not only a high-performance solution but also an environmentally responsible one. Its components can be disassembled for material-specific recycling, ensuring minimal environmental impact. The reduced torque requirements and smaller actuators contribute to energy savings, enhancing the overall efficiency of industrial operations.

Conclusion

The INFLAS® butterfly valve by Ebro Armaturen is a game-changer for industries that handle highly abrasive or sensitive media. Its inflatable seat technology, coupled with innovative safety features and versatile design, ensures superior performance in even the most demanding conditions. Whether in bulk goods handling, pneumatic conveying, or the food industry, the INFLAS® valve combines reliability, efficiency, and sustainability, making it an indispensable tool for modern industrial processes. With its robust construction and cutting-edge features, the INFLAS® valve sets a new standard in sealing technology, delivering long-term value and peace of mind.
