Alloy Steel Butterfly Valves, Electric Actuator, Metal Seated, Tri Eccentric

Features of high temperature butterfly valves

1. It still has stable sealing performance under high temperature and high pressure conditions. Its special sealing system can ensure high sealing performance in all temperature ranges from ultra-low temperature to ultra-high temperature

2. The three-dimensional eccentric sealing system and the optimized design of the valve make the opening resistance of the valve small. The sealing surface of the disc is an upwardly convex cone. When the disc is opened, all points on the circumferential surface of the disc are simultaneously separated from the sealing ring, and it is not easy for solid objects Accumulation on the sealing surface. The valve closing process is completed by the elastic pressure of the sealing ring.

3. There is no phase jam between the butterfly plate and the sealing ring.

4. The sealing performance of the valve is not affected by temperature changes.

5. The shaft diameter seal of the valve stem adopts a graphite press-formed sealing ring. In summary, it ensures zero leakage, and the metal seal plus zero leakage before, during and after the fire, so it is intrinsically fire-safe.
