Valve and flange don’t match? Please tell me?

Flange (RF) DN8002 pcs 20# JB4726 SH3406 PN2.0 RF WN T=12mm Butterfly valve D23HR-J184 DN8002B61 pcs A216-WCB Valve core: 13Cr CL150 RF API609 I applied for two batches of materials such as three-part flange connection. The first batch of flanges and valves can be connected, but the second batch, the valves and flanges cannot be connected (the valve has 28 holes and the flange has 48 holes). Can any experts please give me some advice? ? ?
20# JB4726 SH3406 PN2.0 RF WN T=12mm: Your JB4726 is the material standard of the Machinery Department, SH3406 is the petrochemical flange standard, A216-WCB valve core: 13Cr CL150 RF API609 flange connection three-offset, is the API butterfly valve standard, these two are different specifications, of course they are not compatible! !
Are JB4726 and SH3406 a bit contradictory? Why are there two different standards?
I don’t understand what you said about the second batch of flanges or valves, but I checked that the PN2.0 MPa of SH3406 and the American standard CL150 have the same connection size. There are 48 bolts, so they should be able to connect. It is possible that you bought the wrong material, or the manufacturer supplied the wrong product.
JB4726 is the material standard and SH3406 is the flange size standard, there is no contradiction.
The poster's standards are correct. It must be the manufacturer's supply error. Just ask the manufacturer to return the product.
Check the pressure level of the valve, there may be something wrong there
3# water800925 There is no contradiction. One is the manufacturing standard and the other is the size standard.
4# odin999 I think so too, thank you
6# guanwutang Now I have a question. I asked the design institute. They said that API609 is divided into A series and B series. He told me that A and B series should be added. Do you think we should add them?
There should be no problem with 1# huaiqiang. The standards are different and the holes should be the same. It is probably the manufacturer's problem. Buy from us next time and I guarantee you won't make such a low-level mistake. Haha, contact me at 13861452718
