Load-sensing proportioning valve

[K30_dump]

Hello all,

Thinking of running a load-sensing proportioning valve on my K30 dump project. Never had one on any of my trucks, but have acquired one from a junkyard C30 and am wondering what the benefits may be. Anyone here running one? Opinions?

I am slightly confused on how they work though. I assume they still require the main proportioning/combination valve. If thats the case, how will the valve make more pressure with more load? I guess what I'm asking is this. The load sensing valve cannot produce more pressure, correct? It can only lessen the pressure with lesser loads if I understand correctly. That in mind, the load sensing valve will not provide better braking performance with heavy loads, just make the brakes less touchy when empty?

Sorry if this seems simple, just trying to understand it . Opinions welcome from those who have run them...

Thanks,

Joe
