Sticky Gas Valve

chaosrealm93 · October 17th, 2009, 12:56

hello all. i got my gun about 2 months ago. it was a KJW Hi-Capa KP-05. i recently got another mag for it and i noticed that the mag that came with the gun had a sticky valve. meaning when you go to physically press on it, it would take some time for it to spring back to its starting position. where as the new mag has good spring tension and springs back right away. is this normal..... due to wear and tear? where can i get KJW KP-05 parts? thx. =)

Work some unsticky silicon oil into the valve, it should help.

chaosrealm93 · October 17th, 2009, 13:27

can you recommend a brand? currently, im using the little bottle that came with the airsoft innovations propane adapter...

I'm familiar with it, should be fine (I use it myself when out of the normal stuff I buy, which is 20-30 weight). If you buy yourself, get those weights, purchase at any hobby shop as "RC Shock Oil". Usually cheap, maybe $5 per bottle.

Just did this to all my mags for normal maintenance. Remove the entire valve from the mag (they unscrew) and work in silicone oil everywhere while the button is depressed and give it a few compresses and work in some more silicone oil. I found putting oil on from the exterior couldn't get into the tight spaces so it's best to dissasemble the whole thing. Replace and put silicone oil on the rubber gasket. Let sit for a minute while you put the mag back together, refill with gas. Heat up the mag in your hand a little bit and then put one mag through it and the valve should be working freely and should not be leaking either.

@ SHOCK, how do you disassemble the valve? i can get it out of the mag, but that's about it, the manual isn't very comprehensive and doesn't tell you much other than the working mechanics of the gun.

Thenooblord · October 17th, 2009, 17:26

you dont need to disassemble it, just take it out and pour oil in it, and push the button a few times

chaosrealm93 · October 17th, 2009, 17:32

oh. ok. btw, do i even need to add lubricant to the valve? it seems like the propane already has some lubricant mixed in.

Thenooblord · October 17th, 2009, 17:34

you have to add oil to your propane, too
propane is dry

chaosrealm93 · October 17th, 2009, 17:35

oh. idk, whenever i go to fill the mag, the gas that bleeds from it seems kinda wet and leaves a residue that smells and is kinda moist for a split second... i guess thats the liquid propane huh?

compared to what it feels like it actually has a relatively high boiling point that is somewhere around -40 so it does last a short while in its liquid form (as in it does not instantly vaporize), so that is probably what you are feeling.

chaosrealm93 · October 17th, 2009, 18:11

@ Bissa: ah, thank you

SHÖCK · October 17th, 2009, 19:14

Green gas has lubricant added to it. Propane does not. What you are seeing is the condensed liquid propane before it goes into phase change into a gas. It's super dry and will dry out your o-rings unless they get proper lubrication. If you run green gas, you might be able to avoid this.

he has the converter, so I assume he is using regular propane like Coleman or something like that. as the instructions say, put 1-2 drops into the tank for every 8 mags worth of gas that you use.
