What is the difference between gate valves Z26R-N114 and Z26R-J101?
Referencing JB/T 308-2004 \"Method for Compiling Valve Model Numbers\", I wonder if an answer can be found.
This numbering system does not follow the naming rules specified in JB/T 308-2004 \"Method for Determining Valve Models\", but rather it is a rule set by the engineering company itself; it is necessary to consult the relevant design documents.

It’s a US standard Z-type gate valve with a pressure rating of 150LB and a 6-type design; the valve cover and the gland are connected via bolts, it has a stem-mounted design, and the flanges are of the R RF type. The valve body is made of A351-CF8 material, while both the sealing surface and the stem are made of 304 stainless steel. For the second valve, J1, the valve body is made of A216-WCB material, and both the sealing surface and the stem are made of 13%Cr stainless steel. The only difference between the two valves lies in their materials
