Can you tell me how is the solenoid actually connected to a pressure cylinder? If I wanted to operate two items? What is the Max. pressure the cylinder can be OR do you have to reduce the pressure going to the solenoid? I was thinking about another application where pellet gun disposable cylinders could be used as the pressure supply.Comment

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

If you have extra manifolds on hand, I’d love to purchase one from youComment

Thank you Sir!Comment

Could you Sir; HWSNBN tell me where those solenoids 2 port or 3 port versions you used?
Could I also get 3 manifolds that hold 2 solenoids each? Let me know the cost.
Please/ Thank You

Success! Found an old manifold blank -- good for many solenoids closely mounted together, as well as a five solenoid manifold complete with nipples and mounting hardware.
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

George, they are 3 portComment

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.....

George,
I found them on flea bay. Here’s a link:
