Ok, I have search the internet and here. I have come up with the three common valves that control the steam injection.
1 -> Bash Valve
2 -> Check valve used in reverse
3 -> Read switch with a solenoid valve.
Now the check valve and the bash valve work in the about the same mannor. Witch one is the best?
I would think that the solenoid valve would be the best with the read switch. On the fact you have some more timing options with it. Give some input.
