From what I have found you don't need it and it's what failed on mine. It was squirting brake fluid out of it every time you put on the brakes. The seal failed!
I also talked to several vendor's and fellow car guy's who I trust and they all said if your running rear disc and the rear lock up before the front is the only time to use the adjustable valve. Mine does not.
According to the vendor I bought the proportioning valve from it's a straight through valve. No need for the adjuster.

One more note:
Has anyone had the gasket for the master cylinder to shrink and start leaking? This is a Chrome aftermarket one.

Is this a pic of the one that failed?
