American standard valves
Thread Content
VJR2AD00 DN150 CL150 RF stop valve, DN50 CL600 RF; VQR4AD11 ball valve, DN150 CL150 RF; VZR2AD00 gate valve. These are the only parameters available for quoting. I can’t understand the specifications and model numbers. Is there anyone who can understand them, or does anyone have the valve specification sheet with coding instructions? Thank you.
DN150 denotes the nominal diameter； CL150 indicates a pressure of 150 pounds (equivalent to PN2.0MPa) ； RF stands for the convex surface (the sealing surface of the flange); I’m not sure about the others. I hope this is useful to you.
https://wenku.baidu.com/view/c342dfd35122aaea998fcc22bcd126fff6055d50.html Explanation of American standard valve models. Very detailed.
3 valves. 1. Globe valve: Model specification: VJR2AD00; Connection type & class: DN150 CL150 RF. 1. Ball valve: Model specification: VQR4AD11; Connection type & class: DN50 CL600 RF. 3. Gate valve: Model specification: VZR2AD00; Connection type & class: DN150 CL150 RF. The material can be confirmed – it should be the sealing surface + ST.
It is difficult to provide a quote without specifying the material of the valve body and valve core. AD00 and AD11 likely denote the material; however, different design institutes use different notation methods, so it is necessary to ask the party requesting the quote to clarify the material used.
I’ve learned it, thanks for sharing the materials!
