The 50FJ-1.6PA2 stainless steel globe valve is a manual valve in the hydrogen system, and its first layer of sealing is formed by using hydraulic formed corrugated pipes to ensure zero leakage of the valve stem seal. The second layer of sealing adopts polytetrafluoroethylene packing, which increases the reliability of the sealing.

 

The sealing failure of the valve core and seat of the  50FJ-1.6PA2 stainless steel globe valve with a large diameter is a major problem that is prone to occur during the use of corrugated pipe sealing globe valves. Among users who use large-diameter globe valves in daily life, there is often a problem reported, which is that bellows sealed globe valves are often found to leak on media with large pressure differences, making it difficult to close tightly. The reason for this problem is due to the structural design of the valve and insufficient horizontal output torque. To avoid this factor, it is necessary to choose a valve that matches the on-site design, that is, the matching valve in the original pipeline, and do not replace the manufacturer randomly.
