These valves open with a 90* twist of lever. They are the cheapest valve you can get, but also (typicaly) yeild the worst preformance. (due to the slow opening time) The flow of a ball valve, however, is quite good due to it's strait-through nature. This will tend to even out the situation in cannons with very long barrels (and thus long barrel dwell times).

Openning time can be shortened by:

  • Using of a spring, or a pneumatic ram to actuate the valve
  • Applying dish soap to the moving part... not oil, because it can damage the seals. This lubricates it, making it faster and easier to open.

However, there are better ways to performance; you could use a butterfly valve, piston or diaphram valve, or a burst disk.
