### ⭐⭐⭐⭐⭐ Easy 12v control for water main
*by W***C on September 12, 2019*

I bought this valve to use on the water main for my new house.I chose this model because:1. It will not auto-return (ie, change position) if we have a power interruption (our well may lose power, but we have a pressure tank)2. It works with safer low voltages (I've seen other valves using 120-240VAC!) Much easier to deal with 12v from a homebrew control system as well as safer.The specs indicate that the actuator automatically powers off once the desired position is set. This is good, but I prefer to build my controller so it only applies voltage when changing positions. In testing the unit received with a 12VDC supply, I found alternate wiring that works: Connect Black to the negative (or ground) terminal. When 12v is applied to the Green wire, the valve opens and remains open when voltage is removed. When 12v is applied to the Red wire, the valve closes and remains closed when voltage is removed. This model doesn't have feedback wires, but simply controlling the time voltage is applied should be fine.There is a means provided to mechanically open and close the valve. It is slow, but OK considering that it should never be required. Because of my use on the water main, I got this manual valve https://amzn.to/2ZT54xY to put upstream of the motorized one. If I am in the mechanical room and find a water leak, I need to quickly and positively shut it off separately from any automation.

### ⭐⭐⭐⭐⭐ Exactly as described
*by M***O on February 20, 2025*

Fit was prefect recommend this product very well made

### ⭐⭐⭐⭐⭐ Works Good
*by G***Y on December 8, 2021*

My application was for an isolation valve between two tanks where one gravity drained into another. I originally used an inline sprinkler valve that leaked and overflowed the lower tank bsecause what I believed to be lack of back pressure. This ball valve solved that problem and was a drop in replacement for the 24VAC control signal. I can't speak for longevity at this time. The position indication was a bonus, but I did not use.
