1. The Electric butterfly valve,also called Electric actuated butterfly valve still has stable sealing performance under high temperature and high pressure conditions. Its special sealing system can guarantee high sealing performance from ultra-low temperature to ultra-high temperature.
2. The three-dimensional eccentric sealing system combined with the optimized design makes the valve opening resistance small. The sealing surface of the butterfly plate is an upwardly convex cone. When opening, the points on the circumferential surface of the butterfly plate are simultaneously separated from the sealing ring, and the solid matter is not easy. Stacking on the sealing surface. The valve closing process is completed by the elastic compression of the sealing ring.
3. There is no phase-card phenomenon between the electric butterfly valve and the sealing ring.
4. The sealing performance of the valve is not affected by temperature changes.
5. Electric butterfly valve stem diameter seal uses graphite press forming seal ring. In summary, it ensures zero leakage, metal seal plus zero leakage before, during and after fire, it is essential fire safety type.
