3/8 inch 12VDC 24VAC/DC 3 Way L Port Stainless Steel 304 CR502-B Auto Return Electrical Position Feedback On/Off Motorized Ball Valve

I attached some pics of the indsides in case you are like me and want to know what the inside looks like. You can see there is a screw under the manual knob sticker.All In all I really like them I do have a few complaints1st the 3/8 valves though bore is the same size as the 1/4. And in my opinion is way to small for 3/8 npt.(really should be 10mm not 6mm)2nd I wish they had a valve option that didn't auto return but would return when you revered dc polarity, I do understand that would make the valve only dc compatable.3rd and lastly I wish this valve was offered in a orb(oring boss ) fittings instead of npt... npt is kinda junk for automotive use.I am using this valve for my dual fuel tank on my 97 ford 7.3l truck, I added an electeic fuel pump and the stock tank selector was restricting flow causing the pump to whine when pulling from the rear tank. So I'm hoping this valve last. I'm kinda afraid that the truck vibration will break the insides so we shall see. Another major thing I like another this valve is that it has a manual control so if the board does die I can still run my truck. I also like the fact that the motor turns off after valve is switched, I was going to use a solenoid but I don't like that face that the solenoid pulls constant amps in any direction. Like I said the product seems well made and I'm happy, I just hope it last.

Only reason you didn't get 5 stars is the schematic and instructions are very poor quality. Otherwise the valve works great. Suggest schematic to have valve stay in current state when power is removed or revamp the valve to accommodate this feature.
