Valve selection issues in catalytic reforming 1

Issue 1 regarding valve selection in catalytic reforming: What are the key considerations when selecting the on/off valves for adding and removing catalyst from the catalyst hopper? As we all know, UOP recommends using Metso’s Neles switch valves here. So let’s discuss why this brand is preferred, or what key technologies give it its advantages in terms of selection
The medium is solid – think about what the technical advantages are Durable! It also has the ability to seal valves with powder, as well as the capability to control valve leaks
It would be best if you could explain, in light of the characteristics of these valves, why other valve manufacturers are unable to imitate them
It’s not necessarily impossible to imitate; it’s just a matter of lifespan. Some domestically produced valves can now be used in more severe coal chemical processing conditions. What is the type of control valves for adding and discharging catalyst from the catalyst hopper? Ball valve? Or a disc valve?

Does this ball valve operate frequently on a regular basis?
Not frequently, only used when adding a catalyst
