Triple eccentric butterfly valve

Triple-eccentric butterfly valves DN80 to DN500 - with gearbox or automated

Triple-eccentric butterfly valves are high-quality industrial valves that have been specially designed for use in demanding applications. They are characterized by a design in which the axis of the valve disc is offset in three planes relative to the center of the body. This design minimizes friction between sealing surfaces, reduces wear and provides excellent sealing efficiency even under extreme operating conditions. The metallic seal allows for high temperatures and pressures up to 50 bar.

Features:

  • Triple eccentricity: the special geometry ensures that the valve disc opens and closes without contact with the sealing surfaces, which ensures a longer service life and reliable operation.
  • Metallic seals: for high temperatures and pressure ranges
  • High-quality materials: the body and valve disc are made of corrosion-resistant materials that are matched to the specific requirements of the media and operating conditions.
  • High level of tightness: Depending on the design, they meet the requirements for freedom from leakage in accordance with standards such as EN 12266 or API 598.

Advantages:

  • Long service life and low maintenance due to reduced mechanical stress
  • Suitable for high temperatures, high pressures and aggressive media
  • Space-saving and lightweight compared to other shut-off valves
  • Quick and easy installation and operation, even in automated systems
