Most paintball fields dont allow PVC air chambers on their fields for insurance purposes.....This may be the reason his chamber is steel , not because of high pressure applications.....My mortars are all steel chamber also because they are much more durable than PVC and the Pulse Valve that I use is...

These look to be LP gas service valves and are rated for very low pressure applications....25 psi max........You should be looking for the Asco dust collector valve as I have picked up several on ebay cheap, and they do pack quite a wallop .

Even if he made a mistake and really meant in feet , this would be unbelievable.

Well, No.........I own a paintball field and specialize in putting on very realistic wargame scenario's........This was one of the most intense games we ever did ...The only way to take out a suicide bomber before he detonated the vest was with a head shot......The small air cannons in the back pouc...

Boy would I love to see the expression on the Rainbird CEO's face if he saw the suicide bomber vests I made from his sprinkler valves.....LOL.....

Hmmmm , Maybe you should patent one MrCrowley....Please make it out of aluminum and be rated for at least 250psi.

Yeah , No doubt sprinkler valve manufactures would start putting warning labels on the boxes if they only knew what we were doing with them...lol...Not for use with cannons , paintball mines, LAW rockets, Spudguns .....the list goes on and on.

This is exactly my point guys, you are using a double standard here regarding these valves....If your PVC air chamber is rated for 260psi and you say to be on the safe side never go over 90 psi........Why would you take a PVC sprinkler valve to 150psi when when this is its max pressure rating......I...

Lets not be hasty with sprinkler valve psi ratings.....These valves are not made out of some super plastic that can withstand tremendous amounts of compressed air pressure ....They should be subject to the same safety standards that you use for pressure rated PVC pipe......They may be rated safely f...

You can make one easy enough by using ideas from this site as long as you fit the ammo to the barrel.......Most fields wont allow you to use grenades as ammo for a launcher however as they are too heavy and can knock a paintball mask off during play....Prefered ammo is sabot'ed paintball grapeshot o...

Yeah Peeto, I work in a chemical plant where pnuematic instrumentation and valves makes up a major portion of the systems that I work on.......You would not believe some of the stuff that we have there......I am constantly looking for stuff to use on launchers.......LOL......Keep_ it_ Real.....The s...

You should keep your eyes open for the 1 1/2" Asco dust collector valves that were posted on the forums a few weeks ago....These valves are specifically designed for pneumatic applications and have much higher flow coefficients than modded sprinkler valves...These valves are very commonly used in ma...

These valves are made in China and are not rated by the same standards that some of the other more well known pnuematics manufacturers use as their benchmarks for performance......Most of the other QEV manufacturers list their lower temp range @ 0 F or lower......You may be better off getting a Delt...

The 160 fps is for LAW type launchers only, because the projectiles are fired on a horizontal plane and can accidently hit someone at close range and knock their paintball mask off during play......The velocity allowed for mortars and artillary cannons on my field is much higher because they are fir...

Peeto , check out the new Tippmann bottomline regulators at http://www.firstcallpaintball.com/pages-productinfo/product-3358/tippmann-tippmann-bottomline-regulator.html...They are for air or CO2 and regulate 0-850 psi.......They are very small and compact and you can buy 5 0f them for the price of o...
