Bellows Sealed Globe Valves
The valve stem of the bellows globe valve adopts a double sealing structure of bellows and packing to ensure a leak-free seal at the valve stem. It is used in power stations, natural gas, ammonia, vacuum, refrigeration systems, hot oil, and hot water systems, and is especially suitable for flammable, explosive, toxic and precious media pipelines.
Structural features of sealing bellow globe valve
1. The product structure is reasonable, the seal is reliable, and the double sturdy and durable bellows seal design (bellows + packing) ensures zero leakage of the valve stem. No fluid loss.
2. The sealing surface is surfacing with Co-based hard alloy, which is wear-resistant, corrosion-resistant, good in friction resistance and long in service life.
3. The valve stem is quenched and tempered and the surface is nitridated, which has good anti-corrosion and anti-friction properties; the valve stem lift position indicator is more intuitive.
