USAGE
With use of the most advanced level of both at home and abroad, Three Eccentric Butterfly Valve is designed to be a three-dimensional eccentric multi-layer dual-way hard-sealed butterfly valve and suitable for petroleum, metallurgy, electric power, chemical industry, coal gas, construction, municipal projects etc.
Features
1. Compact structure, small volume, light weight, flexible operation and easy repair.
2. Use the three-dimensional eccentric principle for design, the disc seal-ring is formed as soft-hard layers pile-up metal sheet, features the dual merits of both metal hard seal and elastic seal, and whether at a low or high temperature, keeps a reliable performance without leakage.
3. The seal surface is made of build-up welding of Co-based hard alloy, wearable.
4. With use of the three-dimensional eccentric structure, three is almost no friction between valve seat and butterfly board, resulting in a long duration.
