The last one looks like a self-acting control valve
:'(It’s that difficult?) . Actually, they are domestic drawings, but these valves don’t have a legend on the first page for me to refer to
I was wondering if there are any resources such as comprehensive catalogs of valve symbols that I could refer to?
There are many experts on the forum; let’s see if I know any of them
Guess: The first 803LP is the pressure tap for level 803； The second 811VZ is valve position 811. I don’t know about the others.
