What does FB mean by “piercing the eyes”?
Thread Content
Today, I encountered a problem with a valve in the flowchart; the valve is labeled FB. I’m not sure what that means, so I checked the diagram on the home page and found out it refers to a through-hole. But what exactly does a through-hole mean? I still don’t know. I’d appreciate some advice from those who are more knowledgeable
Why hasn’t anyone replied yet? I’ll post my own reply; hope it won’t get buried
Valves marked with FB are full-bore valves, while RB denotes reduced bore; is FH used for through-bore valves?
You should mention what type of medium and what kind of valve it is. (Blah blah to fill space, ignore it)
No, FB means FULL BORE in English
The medium is demineralized water, and the type of valve is a gate valve. I’m not sure if this information is sufficient to make a determination
That means a full-bore valve. . FB stands for full bore, while RB stands for reduced bore. . .
May I ask under what circumstances should full-bore valves be used? Thank you
The selection of this valve is primarily determined by the requirements specified in the PID, as well as the notes related to that specific pipe grade in the pipe grade table; these notes usually provide clear indications
Take a photo and send it over; are there any other markings as well?:victory::victory::victory:
