kelsey hayes part and proportioning valve

It is a standard block not a disc setup. Unless you have the separate hold off as previously shown.
ok..i think everyone has been telling me wrong then..so all i need is that small hold off valve that has 1 line in and one out and then im good to go? Everyone keeps saying i needed the proportioning valve that looks just like what i already have so..and i ordered on a few hours ago before i discovered i already had it..
