Nice breakdown of the valve. I wish you would consider calling the valve "pressure regulating valve". It might go a long way in educating people on the correct name of both the round hold off valve and the frame mounted pressure valve.

I used both terms in my autopsy and new rebuild articles. I'm hoping that by using "proportioning" in the titles people will see which of the valves is really the proportioning valve. Here's a link to the rebuild article:

I have had both valves apart before during restoration work. Fortunately I was able to clean and re use all the cup seals. The o ring gaskets are easy to find.

They're easy to find in the wrong material. The common Nitrile/Buna-N o-rings that you can get at your local auto parts stores are NOT compatible with glycol-based brake fluid. DOT-5 silicone-based fluid is a little different, but since EPDM rubber is compatible with both types it's what I use in my seal kits.

I think there is a need and a market for a correct and functional seal kit for both the Hold off valve and the Pressure regulating valve. I would bet some of the Camaro parts place's would like to offer them. You might even just offer them on ebay with a BIN price ? I think photos of the valve apart also would go along way in selling a kit.
I would gladly pay $30.00 or more for kits that are complete and correct.
Are you doing a breakdown of the round Hold off valve also ?
Great work and thanks for sharing.</div></div>
Thanks for the feedback, Mike. If I can get my hands on a metering/hold-off valve to take apart I'll see what I can do.
I just added a seal kit to the products I'm selling on my site. I'll post a link in the "parts for sale" forum. I think you'll like the price.
