Pneutronics Valve
By Karl Petersen
This is an industrial valve for high pressure pneumatic device control. It is rated at 100psi because it has fairly small orifices. I believe the od of the nipples is about 3/32" and the holes 1/16". This allows it to pass perhaps half the volume of an organ valve, but it could be placed very close to the action valve due to its size. The unit is about .6 x .6 x 1.5". For those of you with excellent imaginations, I will attempt a sketch:

to the armature area. The tube is brass as are the nipples.
Actually, the armature is a hollow tube and has the rubber molded straight through, making a retained rubber dumbell. You obviously don't need all the ports for operating it as an electric primary valve.
The advantage of this valve, other than its size, is that I have a carton of about 120 of them! I believe it operates well on 0.5A at 12VDC, and is commercially available at an exorbidant $16.
Hopefully Wizard Tonnesen can vet this for us and I can either use them on my Ampico B or sell them off to someone who wants to build a 100psi calliope with a very small rank of pipes suitable for a canine audience. |
