David, After some searching I found the company that makes the miniature solenoid valves that you used in your meticulous crafted torpedo launchers that used this tech. Thank you again for taking the time to share the amazing work you’ve accomplished. I can see the fruits of the many hours you’ve spent developing these mechanisms.

I like these over the Clippard 7mm and 8mm miniature solenoid valves I was looking at earlier and considering using. They’re available in a voltage already compatible with the TCP unit for starters. No need to boost the voltage signal to use the Clippard units.
Ordered a few to test them out. Look forward to getting them in a week or so. Will still need to work out the designs for the pneumatic cylinders, linkages and launch valves with the basic desired functionality logic I posted earlier. The years I spent developing and producing miniature engines has got my brain working over time thinking of all the mechanical valve possibilities to make the logic work. Fun!

A manifold would need to be made with tube connections for these specific valves as they are designed to be face mount. Can’t comment on the max cylinder pressure but these valves are rated for 15psi max. A pressure regulator would need to be used if you plan to use disposable Co2 cartridges. This is what I originally had in mind to charge the pneumatic torpedo system but I’m not sure if I am going to pursue that anymore.Comment

I've got pounds of torpedo and launcher stuff rotting in the sheds -- it all will wind up in a landfill eventually. Anything else I can slip into the box for you?
E-mail me your mailing address and I'll get them off to you tomorrow. dmeriman@aol.com
Love your work, sir.

That’s awesome! Thank you so much sir! I just sent you an email. Btw, the solenoid valves showed up earlier than expected. Arrived this afternoon. Wow they are tiny when you see them in person!Comment

Neat little cartridge type poppet valve that showed up today made by Clippard. Fits and seals nicely inside 13/32” K&S brass tubing. At this stage of the launch tube design, this is what I’m thinking of using to send compressed air to each tube once the pneumatic piston opens that tube’s door.
The pie in the sky idea here is to somewhat isolate each stage of the launch sequence for each tube. I’m trying to get as Rube Goldberg as I can here.
The launch tubes have a floating piston inside of them that the tail of the torpedo locks into via a slight interference fit on the tail fins. The velocity at which the piston reaches the end of its travel in the tube allows the torpedo to continue forward while the piston stops in the tube due to the force on it switching from pressure pushing to vacuum stopping. I know from tests it take 20ml of low pressure air to push the torpedo out of the tube without sending the floating piston Inside the tube with it due to this effect demonstrated in earlier posted videos.
My ideal situation would be to isolate the stored air for the piston tube launch circuit with a poppet valve. This way I can pre charge each tube with a measured amount of low pressure compressed air that will be released to the tube once the poppet valve is triggered.
If I can accomplish this the high pressure side of the launch mechanism will limited to just the pneumatic pistons and solenoids for opening each tube’s doors before triggering the poppet valve. Yes this could be done a lot simpler with springs in the tubes and linear solenoids to open the doors but.....
