1972 Satellite Proportioning Valve available?

[Cudatali]

Hello, I just acquired a 72 Satellite with factory front disc brakes, the proportioning valve seems to have failed since I don't get any fluid pressure out of it at the rear brake output. I've searched in Mancini, Summit to name a few and I can't find anything that really matches. Any suggestions where I can find one. Thanks!

*EDIT its a KH9410 FWIW
