Solenoid for t-shirt cannon options

We were having problems with shooting distance or our cannon and are questioning our solenoid. We bought this one https://ussolid.com/1-brass-electric...er-diesel.html which lists a Cv of 12. However, it uses a diaphragm that is less than 1" in diameter and moves 2-3 mm when open. It makes a very loud noise as the air rushes through the small opening and seemed inadequate. Despite the listed Cv, we were doubtful, so we exchanged it for a 1" ball valve that we opened manually. The 1" ball valve shot the t-shirt 150 ft without the noise of the solenoid, the solenoid distance was 40'.
We would like to hear what solenoids or valves other teams are using on their cannons.
Our setup is a 3" cannon reduced to 1" nipple into 1" solenoid, teed into a 1.5 gallon accumulator tank through a 3/4" reducer.

Re: Solenoid for t-shirt cannon options

We are using a similar-looking (but with no obvious branding) 3/4" valve that I am 90% sure came from Amazon. As we are moving our air cannon from an AM 31" nanotube chassis to a golf cart, we are considering upsizing to a 1" valve. Obviously, I'll avoid this brand.

Update: Oh - reread the description. The solenoid valve we are using is a 1/4 turn ball valve, not a diaphragm valve. I recommend a 1/4 turn ball solenoid valve.

Likely example: https://www.amazon.com/BACOENG-DC12V...32966631&psc=1

Re: Solenoid for t-shirt cannon options

It appears to say the ball valve you referenced takes 3 seconds to open fully. Have you tested this?
Thanks

Sorry; I thought I posted about this a while back! This is not actually the valve we have. We have one which is a solenoid actuated 1/4 turn valve; the one I suggested above is a motor actuated 1/4 turn valve. The motor actuated variety makes more sense when you are going to have the water/air running for long periods of time as it uses less current, especially when holding each state.

Thanks to your heads-up, we have purchased this one instead for our rebuild. This solenoid actuated spring return style will get quite hot used in that application, based on online reviews, but should switch quickly for the air cannon use case. We have not had a chance to do any serious testing with this one mostly due to thunderstorms on our build days, but it is definitely sub-second to switch.

Re: Solenoid for t-shirt cannon options

We have yet to test the one we bought but have high expectations, it is a MAC VALVES 57D-33-501AA we got it off eBay for around $125. It is supposed to have around open time 23 msec and a closing time that is even faster, it also has a Cv of 17.4. This is a very similar solenoid to the one that the Poofs used on Shockwave. It is more expensive than some of the others that have been posted but should allow for greater control and a more reliable system.

Re: Solenoid for t-shirt cannon options

Please post the results of your testing when you are ready.
We have used this one https://ussolid.com/1-brass-electric...er-diesel.html which lists a Cv of 12 but I don't believe it. We are getting over 100' at shooting pressure of 30psi with a manual ball valve and a 1" sprinkler valve (please do not lecture us about plastic) but when we insert the solenoid from US Solid, we get about 20'. Although a 1" fitting, the actuated diaphragm opening is much smaller.
From the info on their website, 254 shoots at 120psi, which we are a little hesitant about.

Re: Solenoid for t-shirt cannon options

We use this: 1" Asco Red Hat pilot valve #8353C035. It is pilot operated so you need a pilot valve to control it. It meant for back pulsing filters so it is fast and has a high CV (20).
