<p>70.16.86.204: linkage</p> <hr /> <div>[[Image:Ball_valve.jpg|frame|A typical PVC ball valve]]<br /> '''Ball valves''' open with a 90* twist of lever, similar to the operation of a [[butterfly valve]]. They are about the cheapest valve you can get, but also (typically) yield the worst performance, due to the slow [[opening time]].<br /> The flow of a ball valve, however, is quite good due to its straight-through nature. This will tend to even out the situation in cannons with very long barrels and/or heavy projectiles (and thus long barrel dwell times).<br /> <br /> Opening time can be shortened by:<br /> * Using a spring or a pneumatic ram to actuate the valve<br /> * Applying dish soap or other lubricant to the moving part. Oil or oil based lubricants should ''not'' be used, because they can damage the seals. Lubricating the ball valve will decrease friction and will result in a faster opening time. <br /> <br /> However, there is more performance to be gained by using a faster valve, such as a [[butterfly valve]], [[piston valve|piston]] or [[diaphragm valve]], or a [[burst disk]].<br /> <br /> [[category:valves]]</div>
