Appears to be a good valve, no info provided whatsoever
The info that came with the valve was worthless - I bought two of the 3/4" 12 VDC model. I'll update once they're installed. Tested them with a power supply, they stroked just fine, no telling on the flow rate though.The yellow wire is positive, blue is negative.

Reviewed in the United States on March 29, 2022
This is the third one I have installed to replace a manual fuel shutoff valve. One on a Farm tractor and two on riding mowers. It's nice not to wake up in the middle of the night and wonder if I forgot to turn off the gas. Very low price for all that peace of mind.
