96 Accord Coupe 2.2 rear brake Proportioning Valve?
 

My question is if they’re just standalone proportioning valves can i buy standalone proportioning valves and replace them or is there a replacement part i can buy

this is how mine looks

Looks like #31 or #29 is the part in your picture where they come as a set. I don't know if those are proportioning valves as they look like unions for the brake lines.

Why are you looking to replace these?
