Proportioning valve question

Hold off vs proportioning are kind of the same.

Technically hold off is a delay then full pressure to front and back.

Proportioning is 500psi in 100 psi out (made up numbers)

Each MIGHT have the other as part of its circuitry

Thanks for clearing that up. Just more confusion. I'm getting to know it well but that's what makes this fun. I'm learning.
