Features
1. The triple-eccentric butterfly valve is known as a *process valve. This design makes the valve an ideal metal-seated butterfly valve with bubble-tight sealing for high-temperature, high-pressure, and fire-resistant applications.
2. Due to the welded structure, the valve achieves elastic zero leakage with the pipeline plane.
3. This valve has no flange, which brings great convenience and aesthetics to pipeline and insulation wrapping.
