I have been looking into getting a clutch control valve to try and not to put so much stress on my stock transmission. I will be using a clutch masters fx500 clutch and should be making around 450whp when my car is done and running. I saw that clutch masters has a flow control valve and that tilton has one as well. I have researched them both and they both seem to have good reviews. But I was wondering what is the difference from those two compared to something like this, https://www.ebay.com/itm/Hydraulic-I...ox!92583!US!-1

it seems to do that same thing as the clutch masters and tilton flow control valve as far as letting fluid go one way free flowing and restricted the other way. It also has a max pressure of 5000psi which I don't think the clutch pressure is that much. And with this you can adjust the flow precisely to where you want as well.

So my question is that is there something that I am missing about the clutch masters and tilton flow control valve that this unit from ebay does not have? Will this unit from ebay work the same as the clutch masters and tilton flow control vales? The reason is that there is a huge price difference and Im thinking that it is just because of branding and marketing but they do the same thing.
