Building/tuning a STBB

[Psycho91]

If I changed a valve or 2 out which would y'all recommend the balance valve from the vs line or the eko valve

From what I've read, the VS balanced valve is the way to go for low pressure but dosen't work at like anything above 300psi. Or (also for low low pressure) the AKA tornado valve if you're willing to spend the coin. It sounds like at least a couple of your guns already have the eko valve so no point replacing like with like. There's also the magnaport which seems interesting but I've heard it doesn't like going below 600psi. Could be an option for a high pressure build.

I very much like the AKA Tornado valves. AKA designed the valve to be used with stock Spyder springs. One doesn't have to do much work other than fitting some bits to the marker and then dialing in the HPR. My Black Widow is running at 225 psi with stock springs and an unpolished fatty striker. Another nice benefit is this - I've gotten very close to 2000 shots from a 20 oz co2 tank when using co2.

It's the stock valve out of later Spyders. The valve pin is designed in such a way to allow more flow and blowback is provided via a small hole in the valve rather than the valve pin. My hope is to increase volume/flow so therefore I can use lighter springs/striker.

Which later spyders? I've taken apart pretty much everything there is outside of the balance valve and spyders have always had the cut out of the valve stem not a hole in the valve itself

There's a lot of stuff like JT and off brand that run the valve hole but I've never seen it on a spyder

From a quick glance, it looks like it came on the fenix, MRX, MR100, MR5, etc. Here's the ANS page for the vavle body.

I read some threads on LP spyders where people got some good results with these above 400 or so psi. We'll see if I wasted my money or not.

Weird, wonder when that changed because I've had most of those you listed cross my work bench

I'ma try a balance valve then, I have enough stock valves if it gives me a headache

Also me and my niece went digging through my junk trunk again and we found some bodies and a frame that had a battery in it that seems to function just fine it's off of a mongoose, although one of the bodies had a random hole right behind the valve retaining screw plugged why do this I'ma guess it lets excess blow back gas out or something, I believe I got it from a member here that had built a LP Spyder that he couldn't get to work

[Toestr]

Some bodies use a set screw behind the valve to retain it instead of a pin like earlier Spyders.

[Psycho91]

No this screw was added it is not factory

[Psycho91]

This is what I'm talking about

[scottieb]

The hole there vents gas coming through the valve towards the striker. It is very common to plug the hole in LP builds.

[Psycho91]

Looks like the same body had a magna port valve in it only problem is Im pretty sure I don't have the fancy valve stem they come with

[Psycho91]

I take it it will work fine with a stock valve pin

[scottieb]

It will work fine with a stock valve pin.
