U.S. Solid Motorized Ball Valve – 1/2" Brass Full-Port Ball Valve, Normally Closed, 9–24V AC/DC, 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.

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.

The valve worked as advertised & expected for 3 weeks. Now, it will not completely close when powered off. It is advertised as automatic shutoff with no power needed. With the valve hooked to my outside faucet and water supply on the valve will continue to leak until I turn off the water supply. I am not a valve mechanic so I have not attempted to work on it other than check for any noticeable dirt or obstruction that would keep it from closing. I saw nothing.

Bought 1" brass motorized 2 wire with manual function in 2020 for fuel transfer (gas). Worked great for 4 years (around 30,000 miles). Thanks to our great bridges, the clifts on and off, the gear head broke off. Due to time restraints replaced it with a stainless with same functions. Lasted well, untill the first time I used it. Took the seals out. Thankfully I had placed an emerg. shutoff above it. Ordered another bass valve identical to the orignal without the manual function. Same story. Replaced the gearhead on the orignal brass valve an so far so good. Think tolerance, these valves are blowing the O ring up past the nylon seal and jamming the ball. The only reason I didn't give it a 5 star is I have 2 I can't use. ? fuel use. but was told by the manufacture per phone call I was good to go back in 2020.

Came fast, installed easy, works great.

I've used other brands and types of electric valves, both - 110v-or-24v for the air valve on my compressor and this one is the best. It opens and closes smoothly .The extra bonus is that it does not create heat when it's opened or closed. It's a great valve and I will definitely buy this type in the future.

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.
