Dear,
It looks like instrument air regulators and filters not sure.I think you can ask the concerned plant's instrument tecnicians from where you had this snap.They could tell you.

Since you are new to control valve...I am strongly recommend you take the control valve catalog and find out what are those stuff...

What will you do when you get uncertain answer like " i guess...", "may be...", etc.

Also, open the control valve handbook (e.g. Fisher, Masoneilan, etc), i am sure you will get the answer.
