Good idea, bronco. I haven't seen the China built motorized ball valves with solenoid type action (super cap for auto close when power removed) for very small diameter lines, but I have used them for water and compressed air and have been pretty happy with them except for a some QC type issues with leakers and electronics failures. On my neighbor's propane 8/1 conversion we used them for propane, compressed air unloader, and several for various compressed air lines.
The prices are so good I use them a lot; even 12 years ago motorized ball valves started at $350.
