the 3 way pneumatic valve
Many thanks for the 3 way pneumatic solenoid valve. I used two of them, a regulator and 2 way valve to build a test rig for students of engineering here at Exeter University, UK.
It took a while to work out how they functioned, but when I did I found it easy to build and connect up the rig.
The low price was a great advantage and the system is working well being driven from Arduino boards.

error in assembly illustration
it works very well, however the picture illustrating the assembly is not correct. The long rod supplied is called the reflector, the folded loop diploe assembly (also supplied) is the active element and the rest of the frame contains the directors. The antenna is called a yagi design,
The long rod and active folded loop are illustrated in the wrong positions, the long rod (reflector) should be placed at the back of the folded loop. The hole positions are correct for a yagi configuration with the correct sizes for the reflector, director rods and the active loop.
Look up on google for the correct layout and spacings for a yagi tv antenna.
