I'd strongly suggest getting in touch with have blue to have him explain their specs to you in plain english AND see if you can't get the specification sheets for those valves (I got these when I purchased a couple MSV-2 valves from him). I'll pm you his email.

Now, just for my curious sake, if no one elses, could you give some more details on your autonelson design/build/concept? More diagrams would also be cool I'd love to see how you're thinking of designing everything and especially if it can handle like 10-13bps under normal circumstances without parts getting worn down really fast resulting in the system breaking down, either at the powertube, coupling, pump arm, etc etc.

Thx mate!
Well, according to clippard's site, the smav-3 should be an threeway, I think it works like if you use it N.O, the N.C port acts as the exhaust and the other way around. I'll definitely talk to haveblue!

Well, this is just a design/concept in this stage. My dream is to build it next year. I plan on making the bolt, powertube, valvenut, cupseal, upper and lower "receiver", trigger frame and all the small parts by myself at my school. I want someone else to machine the body, just to get it right. And I will be using a modified phantom hammer. All valve parts and powertube will be larger and more sturdy than stock phantom parts. The bolt is bore drop so it should handle it better than a phantom bolt.

I haven't finished my design yet, but I will post more and explain later on.

Have you anticipated the known problem with the Nelson Valve interacting with a fast, mechanically operated ram? I recall Palmer had much difficulty with this on the Tornado, and eventually ditched the idea.
I believe the TS-1/AT-85 is the only one to get one that worked somewhat reliably.
Good luck.
The problem with a incoprprated 4/5 way is that the reciever consists of two parts, upper and lower. And the I feel it would be easier to just buy one that works and has a smooth action.

I'm thinking of slowing down the ram with a "flow/check valve unit" (IDK what it' s called in English ) BPS is not that important, I will be using a springfeed on top and I rather have a slower cycle than to put too much stress on the internals.

There's a drawing for an (old) stock WGP 4-way shaft. It might be beneficial to mill your own 4-way, and just use an existing shaft? That way, you could fit it just about anywhere. Just a thought...
I think it would be hard as I said in earlier post, but maybe I'll give it a try. We'll see Thanks for the links!

Even though I owned one year and years ago, I think you're absolutely right - the only auto-nelson (including pump assists) that doesn't seem to do serious damage to the gun's internals/valve system.

In terms of adding the three-way into your gun design, you might also want to look at the hardware/internals for PPS's quickswitch 3-way or whatever it's called. The seal mounts seem like they're be super easy to incorporate into your own design, modular I'd call them. This might be the same case with the wgp 3-way mentioned, so please forgive me it this is being repetitive.

EDIT: from one of the above links, this is what I was talking about regarding PPS's quickswitch
To be honest, I dont really know how the palmer works
