Is this a bladder tank

No, it's a galvanized tank.

But is the water contained within a bladder within the galvanized tank?
Does the tank have a air valve on top of it? (looks like a valve on a
tire or inner-tube)



It's just a galvanized tank. It contains no bladder and it has no
schraider valve on top.
