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

Worked so far. Used it to install on a truck mounted sprayer. Rigged up a simple on/off switch which i can run from the cab. Seems to be solid built.

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.

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.

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.

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.

I'm very impressed with fit and finish of this product. Looks to be built well. I've tested one of them with a 24 volt power supply that i also ordered for my project and it works well. I maintained the power on the valve for approximately 45 minutes and the valve stayed open just as it should. When the power was removed, the valve closes. I also monitored the temperature on the valve and could not feel any heat at all. I'm in the process of installing these valves on my new shower to make it a smart shower. I'm using ge smart switches to activate the 24 volt power supplies for each of 3 valves. One will turn on the regular shower. Another will activate the rain shower and the last will activate the hand shower. I will have a smartthings button inside the shower that will be able to change back and forth inside the shower. I have no normal hot or cold water valves in this shower. The water will be routed in to the valves from a watts thermostatic valve which will be set to my perfect temperature. All this will be tied together with smartthings hub and Alexa. I will be installing a gfci plug that will have a battery back up plugged in and then all the components of this shower will be plugged in to this battery back up. I'm putting a lot of faith in these valves. Lets hope it works! Update!! Valves are working great after two weeks of use. I love my automated shower!

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.

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.
