U.S. Solid Motorized Ball Valve- 1" Brass Ball Valve with Standard Port, 9-24V AC/DC and 2 Wire Auto Return Setup

I've been using this for about a year now to control the CO2 flow for my aquarium. Most hobbyists use solenoids which have a tendency to burn out. This has been rock solid and has worked without issue.

Pricey but solid. they work solid and do make the zippy noise. These are not INSTANT. They take a couple of seconds to open or close. Great for RV tanks as you can barely hear them work. I haven't had one malfunction yet with gray water or debris. I got them on multiple tanks under the RV for almost a year, no problems (I do spray silicon lubricant into each valve every 6 month to avoid salt water corrosion). These don't overheat when left ON ( I leave them open all night when the temp drops below freezing) to empty the tanks and avoid ice damage.

Works great

I originally purchased a different three wire model that tested ok, but failed on the second day of use. (Easy refund at US Solid/Amazon) I opted to replace it with this valve since the other failed "open" and it wasted a LOT of water. This valve basically opens electrically but closes mechanically. If it fails, It should "fail" closed which is more beneficial for my use. I have it acting as a remote purge drain valve for an evaporative cooler. So far working perfectly, I coupled it with a timer which dumps the cooler reservior contents after 6 hours of the cooler running. I like these models that US Solid sells that operate on a variety of power sources. This one will use AC or DC and from 9-24 volts. To keep from adding extra power sources, I just wired the power to operate the valve off my sprinkler timer transformer. If I get another valve failure, I will revisit this review, but for now 5 stars! After a month or so of no issues I plan to buy more of their valve products for some other projects. UPDATE: June 2020, valve still working with no problems. UPDATE: May 2021, valve still working with no problems.

Purchased at end of season 2024, dead by start of season 2026. Definitely not worth it. Hardest part is to have to swap out for another one now.

I actually needed a normally opened valve for my project and not a normally closed one. It can easily be changed, as follows: open the lid and remove the PCB and the little motor drive. Change the two limit switches from location. They easily slide in- and out of their slot. Cut the motor wires and solder them corssed: blue to yellow, and yellow to blue. Re-assemble the motor and pcb, and replace the lid. Done. Now the valve operates as a normally OPEN valve. For such a standard part, I expected that the manufacturer would have disigned a little switch inside the controller box to choose between Normally OPEN and Normally CLOSED operation. But with a little effort it can be changed. Good luck.

Having trouble with undependable swing gate valves? So was I on my RV heating system! Installed this motorized unit and eliminated occasional cold blowing heating ducts! Very simple installation. As soon as system fans engage this unit opens and we have HEAT! No gate valve partially open or not! This units ball valve totally opens or shuts and allows a FULL FLOW of fluid.

I've had this valve in service for a couple of months, and I have to say I am very happy. It seems to be working flawlessly. Installation was a breeze, and the only thing I did was reduce the supply voltage from 24V to 12V and add an LED to show when power was applied. The valve still works great since it is rated for 9V to 24V. It's a great choice for the project over a solenoid valve.

So far so good with these. 2 years outside in cold weather climates and they still work great come springtime.

excellant Produit

I use a wireless relay along with a 12 Vdc power adaptor to drive this valve in the backyard, so that I can turn the water on/off remotely from anywhere on the premises. The system turned out extremely reliable. When the valve is off, there is no leakage at all, thanks to this excellent product!

I hope it lasts because it works great. I'm using this to shut off the heat to the cab in my truck as the heater controls don't shut off all the way and still throw heat in the summer. Just have to hit the switch and no more hot air when I don't want it.

These were total awful. We bought 12 of them spent $1200.00 Canadian. After 5 weeks one quite working then 1 week later another one quite working. We tried to contact Amazon 3 times they totally ignored our emails and would not respond. So we lost out out about $200.00 right away. I'm only hoping we only loose the two not the 10, more we have in our garden. I would hate to be ripped off the whole $1200.00 we spent. Please be aware they don't have any warranty and they don't stay working very long. This company is quick to take your money but will not take care of their customers. Be Aware.
