Steering Valve body. -What does this do?

On my 1991 4Runner v6, on the passengers side frame rail is a valve body.

This vavle body takes the high and low pressure steering hoses from the PS pump, does something with it and then there are 2 lines that go from thise valve body to the PS gear box.

What is this thing?

I'm going to guess that it has something to do with the rear ABS.

+1 on the ABS modulator. Uses power steering pressure to modulate the rear brakes.

Well, I replaced my leaky steering box with a non-leaky variant.

When I did so, I noticed that the bracket that affixes the ABS modulator hoopajoo had broken, and said hoopajoo was being held in place by the hardlines.

Now, after fixing ONE PS leak, I have another one... From the ABS modulator. I think it's the copper crush washers needing to be replaced.
