Solar diverter valve

[aquam4n]

Are you suppose to be able to blow air through the side shown into the opposite side or is it suppose to be sealed similar to a check valve aka 1 way valve?

I have no idea what that picture is of.

Who is the manufacture and model number of the valve?

Can you show more of the valve for context?
