Installing a floating/rocket valve to the KSC/KWA Glock Series

Important note:

  • Retailers use both the terms "floating valve" and "rocket valve" very loosely, both refer to the same thing.
  • The gun that I'm using for this guide is my KSC G19, but as long as your Glock is a KWA/KSC, this guide would work. Full-auto Glocks have a slightly different blowback unit but the valve is the same.
  • This guide is only to upgrade/replace your stock floating valve with a new one. (In case the stock one broke, or you want more power out of your Glock)


As of right now, September 2008, there are 5 options you can choose from.
1- Stock floating valve
2- Hurricane floating valve (comes with the hammer spring/recoil spring set)
3- Shooters Design floating valve
4- Firefly rocket valve
5- R.C.C Rocket valve
5- Airsoft Surgeon rocket valve


From left to right, Top: Hurricane, Stock, and Firefly. Bottom: R.C.C, Shooters Design.

My recommendations would be the Firefly or SD valve. I have built several KSC Glocks with the Firefly or SD valve installed; no complaints. My Airsoft Surgeon valve broke into 2 pieces after a couple hundred shots. I have not bought another one since. It works great before it broke though. I haven't tried the hurricane valve the entire time I've had it. I haven't tested the R.C.C. yet either, just got it a few days ago.

So enough mumble jumbo, let's change that valve. Tools: a hammer, a chopstick, Philips screwdriver, thin punch (I use a retaining pin from my broken KWA magazine). Improvise if you don't have the specific tool(s).

1-Field strip your Glock.

Take the magazine out of the gun and set the magazine aside. Rack the slide back once. And while holding down the front tabs, push the slide forward and off the frame.







2-Blowback Chamber

In order to remove the blowback chamber, we first must remove the spring guide, outer/inner barrel. After lifting out the spring guide and barrels, set them aside. Using a screwdriver, remove the screw that's holding the blowback chamber. (I use a hex screw, but KSC and KWAs use standard Philip screws.) After removing the screw, lift the blowback unit out of the slide.





Treble
3-Loading nozzle

Position the blowback unit as pictured. Carefully pull out the loading nozzle. (be careful not to lose the two springs) The floating valve is inside the loading nozzle, so we're almost there. Using a punch or something thin and strong, push out the pin. Do it slowly so that the floating valve won't come flying out the other end. After you have pushed the pin in, pull it out the other side and out should fall the floating valve. Careful not to lose the floating valve spring.









Treble
4-Putting it all back together

Now the hard part. Repeat everything you have done backwards. Taking your new floating valve, place it in the nozzle. Make sure the valve sits through the spring. Using the chopstick, push down lightly on the floating valve. Using the other hand, push the pin through the nozzle and line up with the other end. Look and make sure the retaining pin is on top of the floating valve and holding it in place. This might take a few tries because the floating valve spring is working against you. You can use the chopstick to guide your retaining pin. The pin should protrude a little on the side. Push it in with a hammer or a retaining pin to make sure the loading nozzle side is smooth.



NO


YES









Reverse the whole process and put your gun back together. The gun should shoot again. If it doesn't shoot, make sure you have done everything I told you to. I tried to make this guide as concise and easy to follow. My first guide so if there are any improvements, please let me know. Hope I helped.

Excellent guide Frank, really great.

Pinned.

Edit: Actually, I'll leave this in the normal section for a little while, as it will generate more views that way. After it is pushed down a bit, I'll repin it.
edenicity
excellent guide, I would suggest pinning if it werent already decided upon.

Excellent guide and nice slide. Got a question though, is an upgraded touch breech really necessary? I can't justify spending $30+ on a small chunk of metal when I've never seen a single stock one break.

Nope, not necessary at all. Redwolf had them for 26.50 a long while back. Since I was placing an order with them anyways, I bought it. I personally don't recommend it because you need to space the breech to the right, otherwise your Glock will fire full auto.

And thanks Pete and edenicity, I've been wanting to do this guide for a while. Someone else made a guide on how to change the valve, but the page has been 404ed. This is my first guide, so if there is anything I can improve on, please let me know.

Thanks Frank for putting this up for me! looks good to me. My only question is where did u get the alan screw?im not a fan of the phillips screw since it strips way too much. Besides that nice guide very straight forward and as u said concise. this should be pinned ASAP. Thanks again!
Treble
I've built 3 KSC G17s and the hex screw came from the G&P slide/barrel set. I opted to reuse the philips screw when I sold the G17s, since not everyone has a hex screwdriver.

Alright, I'll go ahead and repin this now. Frank, if you'd rather have it in the normal section, PM me.

Ah I see. well yea I just got done installing the valve and it seems to do nothing... oh well its in there. btw how do u remove super glue from a surface without damaging the thing that is super glued? I just super glued my sights into place and 2 drops of it went onto the slide from out of nowhere...haha.

You can get "super glue remover" from most any hardware store. Whether or not it will damage the slide, no idea. I doubt it, seeing as I've used it on things as delicate as silk with no issues, but don't use it without reading the warning tab on the box first.

What would be a conservative guess on how much one would gain in FPS by installing the new aftermarket floating valve?

I know this thread is kinda dead, but I wanted to emphasize the importance of installing one of these if you upgrade your flow valve. I installed the Hurricane kit, and, being a newbie to gbbs, had no idea what the floating valve was for. After about 1000 shots, my stock one broke in two. Luckily, I had kept the Hurricane one. Figuring out what was wrong with the gun was a HUGE trouble though. I wasn't a member of ASF then, and had to do everything myself. Eventually, though, I figured out what the valve was for, and how to install the new one, and my G18 is now shooting like a dream again. So, make sure if you're upgrading your flow valve, you purchase one of these along with it.

wow man beautiful gun my g18 is pretty much the same minus the Caspian trades
u know where I can get a slide like that?
Treble
I'm not sure if there are any slides like these for the G18c series. You can start by looking through overseas retailers like Dentrinityshop, Uncompany, Boomarms, Redwolfairsoft.

It's going to cost over 100 when you calculate the shipping.

This thread is great but I do have a question. Can you tell me how to do this on a KWA M26C? It seems the selector switch needs to be removed but I am unsure on the best way to do it. Thanks.

Yeah, I have the same problem with my G18c. I have no idea on how to get the selector switch out. a-confused.gif

Sorry to necro this post but I have the Umarex Tactical Force CO2 COMBAT "glock" and I recently received it today, now this isn't really like a high end pistol, its quite unique and I doubt it has the same internal build as your glock, however my question is, when I got the gun, I took it out of its package and when I moved it around or shook it, it made a rattling sound in what sounded like the chamber, now my question is, do all CO2 and NS2 guns have this "floating valve"? could that be whats making the sound? If the floating valve had broken, would the gun not be able to fire? or would it leak co2?

Thanks for the guide... Not plannign on taking my Glock apart (original KWA, and I've been told its worth a pretty penny)
