The D343H flange-mounted triple-eccentric butterfly valve adopts a triple-eccentric metal sealing structure. The axis of the valve stem is offset from the sealing surface of the butterfly disc, and also offset from the axis of the valve body passage. The rotation axis of the valve seat forms an eccentric angle with the axis of the valve body passage. When opening, the sealing surface of the butterfly disc immediately separates from the sealing surface of the valve seat at the moment of opening. When closing, the conical sealing surface of the butterfly disc only contacts and compresses the conical sealing surface of the valve seat at the moment of closing. Therefore, there is no friction between the sealing surfaces on the valve seat and the butterfly disc, eliminating the possibility of wear and leakage.
D343H multi-layer metal-seated butterfly valve -- Features
1. The D343H multi-layer metal-seated butterfly valve has a compact structure, small size, light weight, flexible, labor-saving and convenient operation;
2. Reliable sealing, achieving zero leakage for gas;
3. The flow characteristic tends to be linear with good adjustability;
4. Adopting the triple-eccentric principle, the sealing surface achieves nearly zero wear, extending the service life of the valve;
5. Wide application range, such as being applicable to media like water, steam, oil, air, coal gas, etc.;
6. Suitable for different temperatures and pressure classes below 6.4MPa, and applicable to various medium pipelines with corrosion resistance requirements.
