What's this logic?

[itsmoked]

I completely and utterly understand the cartridge valve (Logic Element) under B26. I see the pilot pressure coming from the A-Port on the left and know how it relates to the cartridge valve.

What I'm unclear of is what are the three black things in B26. What's the black TEE thingy? Is it acting on the valve or is it just monitoring the valve position? What's the screwy white thing? Does it say R/V? (relief valve??)

I think cartridge valves often have cover elements that create logic and I'm guessing that's what B26 is. Perhaps it's being piloted by the black TEE thing?

I'm going to guess that the TEE thingy is a shuttle valve.
