The D373H multi-level structure butterfly valve adopts a cutting-edge three-dimensional eccentric structure. The butterfly plate's sealing pair is crafted from a variety of high-temperature and corrosion-resistant materials, ensuring optimal performance and durability.
Constructed by expertly laminating and pressing materials, the valve body’s sealing surface is enhanced with precision-welded Stellite alloy and meticulously machined. This ensures the two sealing pairs come into perfect face-to-face contact, providing superior sealing.
Engineered for exceptional durability against erosion, the eccentric structure minimizes friction between the sealing surfaces. This innovation delivers the following remarkable advantages:
1. Exceptional resistance to high temperatures, corrosion, and erosion, ensuring a long operational life.
2. The advanced three-dimensional eccentric structure enables effortless opening and closing, while guaranteeing reliable sealing when closed, achieving zero leakage at the bubble level.
3. The butterfly plate’s sealing pair is designed for easy replacement and maintenance, ensuring continued top performance.
