Diagram for a propotioning valve

Does anyone have a diagram of a proportioning valve for a 72? I removed the large fitting on the rear of the valve and the spring pressure popped out 3 pieces I need to re-assemble it but I'm not quite sure of the order in which to put the parts back in... Any help appreciated!

BTW: It is a disc/drum valve...

Re: Diagram for a propotioning valve

Just had one of mine apart a few weeks ago to clean out some gunk and get freed up. Can you post a pic of the parts, can't describe assembly order from memory right now.

Re: Diagram for a propotioning valve

Here are the pieces that popped out when I removed the rear fitting... So if you imagine the prop valve is on the exteme left do I have the order of the pieces correct?

Thanks!

Re: Diagram for a propotioning valve

Sorry - That looks quite a bit different from the one I had apart, since this is a safety related item, I would rather not guess how that one goes together.
