Schematic for a proportioning valve

Hope everyone is well in these crazy times. I am installing all new brake components and need help with ID and a schematic for this proportioning valve . It came with a bunch of parts with the car. There was a pic on a piece of paper with it and I marked the positions on the valve. I am not confident in The picture I found with the parts. Does anyone recognize this valve and have a schematic for it ?
Thanks for the help. :poke:
