my 1 1/2 dust collector valve puts my piston valve to shame,
opinions????
1. No hybrids - Why not? We're talking about valves not cannons. I'm not aware of a valve on a Spudfiles hybrid cannon that can't be used on a pneumatic.
2. Most powerful - Depends on the cannon, pressure, ammo, definition of 'powerful', accelerant, etc
3. Dust collector - Your dust collector valve is a piston valve (or at least a diaphragm valve), isn't it? Your 1.5" dust collector valve out-performs
some homemade piston valves, not all homemade piston valves.
Apart from those nuances, I'd agree with jrrdw.
Jsefcik, this post of yours is a little troubling. The three issues raised above clearly show that you haven't taken the time to think about what you are saying. The subject of this very topic also indicates the same. Instead of merely absorbing the information relevant to you from this forum, you need to take the time to analyse the information and think about where the information came from, how the information was gathered, what benefits this information give you (how does it help you/how can you use it), and why the information is correct/useful.
Doing this will allow you to answer questions you may have that aren't explicit or mentioned on the forum. For example, from all your months of gathering information about different valves you should be able to list a few key features of a well-performing valve. What makes a valve perform so well? It may have a higher pressure rating compared to some of its competitors, it may open faster than other valves or it may have more flow. You know that the goal of a valve in a cannon is to release the chamber pressure as fast as possible. A valve that opens extremely fast will be better for performance than a valve that opens relatively slowly. Similarly, a valve with a large opening (high flow) can release the pressure quicker than a valve with a small opening (low flow), thus increasing performance (usually). As always there are exceptions to the rule but these exceptions don't need to be addressed due to the vagueness of your question.
By using a bit of critical thought and reasoning you should have at least thought about burst disk valves as a potential candidate. This is because a burst disk valve opens in an instant and, if the disks are cleanly cut, there is almost no flow restrictions. Now I'm not sure if a burst disk valve would be the most powerful type of valve on any given cannon but it is reasonable to assume that it is a likely contender.
