Valve model parameters
Thread Content
I have a few questions I’d like to ask. For example, in gate valves like Z41Y-16C and ball valves like Q41F-20(K), do the numbers 4, 1, F, Y, as well as the material of the valve body, all convey the same meaning?
You can find the instructions for compiling the product model numbers of valves. 4: Indicates the flange connection method ； 1: A gate valve indicates a single gate, while a ball valve indicates a straight-through floating type ； F: Represents polytetrafluoroethylene ； Y: Indicates cemented carbide steel.
Relevant standards are detailed in JB308-2004
Agree with what was said on the 3rd floor; go and check the standard JB/T308-2004. The forum link is as follows: http://bbs.hcbbs.com/thread-254188-1-4.html

What was said on the first floor is very good; just find a valve sample and take a look, and you’ll know It’s also easy to find online
Some are the same, while others are different; for example, the meaning represented by 1 varies.
