<p>Sgort87: /* Pilot volume */</p> <hr /> <div>==Pilot volume==<br /> <br /> '''Pilot Volume is the air that must be exausted so that the force due to the chamber air can push the piston back.'''<br /> <br /> The smaller the pilot volume, the faster your valve will open. Opening times can also be improved by a faster high-flow pilot valve.</div>

<p>Sgort87: </p> <hr /> <div>[[Image:http://www.launchpotatoes.com/images/uploads/mauler02.JPG]]<br /> <br /> The Mauler valve is a commercially available barrel-sealing [[piston valve]] for the use in a [[pneumatic cannon]], designed by Sean Gort of [http://www.LaunchPotatoes.com/ Launchpotatoes.com].<br /> <br /> Independent tests by Sean Gort and John Shell (author of [http://neospud.com/ NeoSpud]) both found that the Mauler valve yields [[muzzle velocity]] superior to that of the [[Supah-Valve]]. A [[chronometer|shooting chronograph]] was used to return muzzle velocity data. <br /> <br /> Both the Mauler and Supah use a lathe to modify the components found in the valve. The Mauler using a wood lathe, and the Supah-Valve using a metal lathe. The difference between the wood, and metal lathe is how the tooling is controlled. On a metal lathe, the tooling is fixed in a mechanism, then moved along linear axises. With a wood lathe the tooling is held in the operators hands, steadied by a tool rest.<br /> <br /> <br /> '''Specifications:'''<br /> * 2&quot; Female NPT Porting<br /> * 1&quot; Female NPT Pilot<br /> * Encased in 2.5&quot; PVC [[tee]]<br /> <br /> <br /> ==Variants of LaunchPotatoes.com Valves:==<br /> For every size variation the valve is given a different name.<br /> <br /> '''NPT Porting:'''<br /> * 1.5&quot; - Shredder<br /> * 1.25&quot; - Ripper<br /> * 1&quot; - Stinger<br /> <br /> ==External Link==<br /> More pictures and specifications of this valve can be found at [http://www.launchpotatoes.com/index.php?act=viewProd&amp;productId=26 LaunchPotatoes]<br /> <br /> [[category:valves]]</div>
