Sprinkler valve quick Q

Unread postAuthor: Blacklockdown » Sat Jul 14, 2012 6:50 pm

ive been looking around and cant find this simple answer:

is the sprinkler valve mod made for a one shot only type deal, such as a potato gun? or can i get pulses of air? because i tend to see them on things that only require a quick burst of all the air. I'm going to make a simple bbmg very similar to this one http://www.youtube.com/watch?v=ME1BcEcB ... 9aJTobjLVA
i just figured the sprinkler valve will give me more air flow

no, sprinkler valves are good for many many shots
when i bought my first one it was 30 bucks,

would you pay 30 bucks to shoot your gun each time?



qev is alot better

You're better off with a QEV, depending on the pilot valve you use you can get either one shot per trigger pull, orconstant pulses.

You can go for a burst fire effect. Something I made a while ago: http://www.spudfiles.com/forums/hp-burs ... 11314.html

Jimmy made one using a diaphragm valve, similar to a sprinkler valve: http://www.inpharmix.com/jps/diaphram_valve_BBMG.html

You can use a sprinkler valve in the same way, and probably keeping it electrically actuated without modifying it as is common is an easy way to set it up.

doesnt that need the solenoid part though? ive already put jb weld through the hole for the solenoid, so that should render it useless


to be clear, the sprinkler valve blow gun mod will stop firing after i let go of the blow gun trigger, correct?

Technically yes - but you need high flow to the valve for it to reclose, so you can't have a thin line to the valve. A 3/4" valve is more than enough.

so i read somewhere that a blow valve is enough for this minigun, since its using a 6mm barrel. what do you guys think? should i use a sprinkler valve, just the blow gun, or even do the mod to the blow gun to make it blow more air?
