Ask for a name of a pneumatic symbol
Ask for a name of a pneumatic symbol
(OP)
Hi everyone,
As I am reading the paper for my work about cooling air path, there is a pneumatic symbol at the end of the air path that I do not understand (there also lack of necessary wording description).
I attach its picture here and the system drawing here.
It seems like a filter but the hydraulic filter symbol has different orient shape.
I also have tried to search for it on ISO 1219 but finding it nowhere.
So I would like to ask if anyone of you has faced it and tell me what it is.
Thanks for your help.

I guess it is a filter as well. But I see nothing similar by searching on various standards.

The valve may be a ball / butterfly / knife gate etc.
RE: Ask for a name of a pneumatic symbol
The right part of it seems like the valve, but what I would like to ask is the left part (the square shape with oblique dotted line).
Have you ever seen this symbol?
