Regarding the selection of valve types
Thread Content
It’s like this: we have a PSA project here, and the contract has already been signed. The control valves to be supplied are to be chosen from one of three options – FISHER, SAMSON, or FLOWSERVE. Could someone help me explain which of these three should be selected? By the way, the supplier later recommended a German brand called Möllert – has anyone heard of it? Since I’m a new instrument technician, I’m not very familiar with this area, so I hope everyone can help me answer some questions. Thank you all
The English name for that German valve is Reitman; I couldn’t find any information about it online, and I’m not sure whether such a control valve actually exists
The choice of brand still depends on the specific operating conditions. Foreign control valves also have their own areas of focus; it is recommended to share the relevant parameters so that everyone can provide feedback
You can ask several manufacturers for quotes and compare them
Thank you for your reply. I was busy at the site all afternoon; PSA is mainly a system used for hydrogen extraction after low-temperature methanol washing. The medium that flows through it is gas, and I will find out the exact components tomorrow and share that information with you. I will also provide details regarding the pipe diameters. Thank you all for your help
I think Fisher is the most professional in terms of control valves; Samson and Fox are also excellent – all of them are world-class
Of course, Fisher is the preferred choice; Emerson’s products are also of high quality. Although I work for a valve manufacturing company abroad that specializes in control valves, I still feel it’s necessary to give credit to the industry leaders.
I’ve learned something, gained knowledge; thank you
Thank you all for your replies; I now have a clearer idea
Has Reitman heard about it?
FISHER’s is pretty good, as well as KOSO’s. For now I’m only aware of these two, and both are excellent
