Residual Pressure Valve?
I posted yesterday about putting a master cylinder on a '93 F-250. I determined that the cylinder was bad so I'm now in the process of changing it. The new cylinder didn't have this check valve looking thing on it that I'm assuming is a residual pressure valve. Its threaded into the rearmost port on the master cylinder. I assume that I need to switch this over to the new one, but what is the thing called and where can I buy one if I want to replace it too?

A proportioning valve, where used, is integral to the master cylinder. It proportions pressure to the rear system.
Here is a Diagram of the proportioning valve:
