Electric control valve
Thread Content
I want to represent an electric control valve at an I/O point on the instrument – what symbol should be used?
EV........................................................
If it’s temperature regulation then.................................
It’s not clear enough. If I understand correctly, it should be represented by DI DO.
It should be DO; and if there is feedback, there should also be two DIs
The so-called electric and pneumatic symbols do not need to be specified in the configuration; generally, the I/O tables in configurations list the tag numbers, with temperatures denoted as TVXXX, liquid levels as LVXXX, and so on.
