Automag Valve On/Off Reference

[Sk8ermog]

Over the years I have had lots of people ask me the difference between Automag valve on/off assemblies. I thought since I had several On/Offs that I should document them and make a thread for others to reference. Consider this like a Wikipedia thread and add any information that I missed or forget to include. Thanks

1. AGD ULT (Ultra Light Trigger/Technology) On/Off
2. AGD RT/Emag On/Off
3. AGD Classic Valve On/Off
4. Centerflag Hyperframe On/Off
5. HSI "Reactor" On/Off


Other Automag On/Off Pictures:

More information to come. Just wanted to get this started for now.

How is the zvalve's performance? Great work

[Justus]

Awesome job! I couldn't identify the classic valve on/off in your first picture because the ones I use have the "new" style top as mentioned in the Reactor on/off advertisement (and shown on the Centerflag on/off). Though I have come across one with those little cross hatches in the top before.

here is some i have saved

Here's few pics of smart mag on/off.

Apparently, I have one of the HCI Reactor on/offs. What size o-ring goes between the on/off halves? One I have came without it.

added my pics

this needs to be a sticky!!!

[captian pinky]

maybe we can just get bunny to add the pics to the article section

Figured it out after looking at some of the pics posted by Superman. Basically double the inner and outer top o-rings. Might have to keep this one.

I also have one of those Venom Wizardvalve tops if a better picture is needed. They were made out of titanium if I remember correctly.

[knownothingmags]

so what's the gimmick what why are there so many variations.

[Sk8ermog]

Different companies trying to "perfect" the mouse trap when the best mouse trap was already made by Tom. Mainly each variation was trying to lighten the trigger and allow you to shoot faster with no shoot-down which was the biggest "issue" with classic mags back in the day. Also most mags were still on CO2 so the less liquid down the powertube the better. The smoking barrel and frozen powertube oring were also some concerns these on/offs were trying to help "fix" but a lot of them actually made the problems worse unless you switched to Nitro or compressed air.

Thought I had a unique one until I saw some more postings of "the wizard". Personally I think this is sticky worthy as well.

This is a fascinating thread. Can anyone explain how some of these small design changes make a functional difference? For example, the Centerflag Hyperframe has it's mid-piece cut in half, compared to the Classic. Why? What would that accomplish?

Also, why did the Classic AGD top change from a crown with points to a crown with a halo?

better flow i think. same reason you see so many variations...apparently they did improve upon the first classic on/off top. also, i believe the centerflag hyper on/off was specific for the hyper frame.

The new classic on-off top is the same top and bottom so you can't put it in upside-down. Installing the top in the wrong orientation was one of the biggest problems with new users (and some experienced users).

[Laku]

That's Venom wizard valve on off top. Works just like normal on off top but is made from titanium(at least that's what I recall) and theoretically higher flow.

[Laku]

You're right, it was the "Thunder" bolt that was partly titanium. Wizard valve is brass, though colored to black when not worn. This is mine from -96 when Venom was sponsoring our team.

[1985phenom]

What on/off is this? It looks like something that was in post 29.

[Cyco-Dude]

regular on/off bottom; some modified on/off top. i have one like that...it just looks like an old on/off top that's had the "cross" enlarged.

Does anyone know how many shims are supposed to be in the stock ULT?

[athomas]

It depends on the tolerance of the parts you have installed. Usually 3 is good place to start. If it works good, leave it at that. If you want to tweak your setup, add shims one at a time until you get bolt stick or an over reactive trigger. Then remove the last shim.

I think mine came with a AGD RT/Emag On/Off, should i just put back the stock one?

What valve is it? I assume it is a classic valve. It really doesn't matter if the assembly is complete. A retro on-off will work fine in a classic valve and will provide a lighter trigger pull. You have to make sure all the assembly is there. If the retro on-off isn't working or not all there, then you can put the standard one back in.

[juit]

It really really loks like the rt, same top and pin

[kknack]

Does anyone recognize the on/off on the left? I know the one on the right is a reactor. I got a bit of a project minimag with the classic valve and a pile of parts.

[zondo]

Looks like a classic on/off but I don't recognize the top.
