These valves open with a 90* twist of lever. They are the cheapest valve you can get, but also yeild the worst preformance. (due to the slow opening time)
Openning time can be shortened, by the use of a spring, or a pneumatic ram.
A ballvalve offeres better air flow compared to a sprinkler valve, thus can be used in large cannons for good performance. For better performance, use a butterfly valve, piston valve, or a burst disk.
To make it easier to open, one can apply dish soap to the moving parts. It is not recomended to use oil, because it can damage the seals.
