Questions regarding valve codes
Thread Content
I would like to ask the experts here. The valve numbering examples in a certain design institute’s pipeline classification table are as follows: for example, for gate valves, it is Z61H-16C2. I have two questions. First: is that the code for the driving method? If it is manual, does it need to be filled in? Second: What does the 2 after C mean? (This design institute is a small one, so it likely doesn’t have its own separate numbering rules; however, JB 308 seems to contain no relevant information.) Thank you very much
First: It’s not mandatory to fill it in; if done manually, the code can be omitted. Second: “C2” may be the design institute’s own code; to find out what it specifically means, it is necessary to ask the design institute. .
That was marked by the design institute itself; isn’t it clearly written in the table? C1 is made of A105 forged steel, and C2 is made of WCB cast steel.

Z【】61H-16C; there may be several material codes within C, and the second digit represents the handwheel, which is omitted here
