The D373H multi-level structure butterfly valve features an innovative three-dimensional eccentric design. The sealing pair of the butterfly plate is crafted from materials that offer exceptional resistance to high temperatures and corrosion.
Constructed through lamination and pressing of robust materials, the valve body’s sealing surface is fortified with Stellite alloy and precision-machined. The two sealing pairs meet face-to-face, ensuring optimal contact and performance.
Designed to withstand erosion, the eccentric structure significantly reduces friction between the two sealing surfaces, offering several key advantages:
1. Exceptional resistance to high temperatures, corrosion, and erosion, ensuring a long service life.
2. The three eccentric structure facilitates effortless opening and closing, with reliable sealing when closed, achieving zero leakage at the bubble level.
3. The sealing pair on the butterfly plate is easily replaceable, simplifying maintenance.
