Solenoid and pilot valve test fixture

[gadget-evilusions]

At my day job I build pop and beer bottling machinery. I am in charge of one line of our machinery that uses around 350 solenoid valves and 312 air pilot valves to control the functions of the filling. I had to build a test stand yesterday to double check the functionallity of some of the valves in house to determine rates of failure. I built it using a prop-1, 2 square D pressure switches with normally open relays, and my valves and test stand.
