U.S. Solid Motorized Ball Valve- 1/2" NSF Certified 304SS Ball Valve with Full Port, 9-24V AC/DC and 2 Wire Auto Return Setup

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.

Came fast, installed easy, works great.

I used this to control the water for an automatic evaporative cooler setup. It worked perfectly all summer exposed to full sun in 115°+ weather. It did not see much rain so I cannot confirm its water resistance.

Installed this valve in my home automation setup, and it's been working flawlessly. The auto-return feature is great—when the power cuts, it closes automatically, which adds peace of mind. The stainless steel build feels solid, and the full port design doesn't restrict flow. Wiring was straightforward, and it operates quietly. Highly recommend for anyone needing a dependable motorized valve

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.

Nice for the price. Much less cost than dedicated water main shut-off valves with a Zigbee or Z-Wave automation interface. You will need a power pack to maintain current to this valve and keep it open. Purchase that separately plus any power switch control that you will have the power pack plugged into for your home automation. Plan to use this valve for emergency water main shut-off during a power outage, flood sensor triggered in the house or garage, or during an earthquake. My water pipes are embedded in my floor cement slab, so I am anticipating the possibility of a break if we have a severe earthquake someday here in Southern California. This valve will shut off through my home automation or security system when a vibration from an earthquake is detected, or one of my five water flood sensors are triggered from my security system. During a normal infrequent power outage I will need to have a 12 VDC battery to open the valve. This valve uses very little current once it is open to maintain the 'Open' state, but it will not remain open without power being applied, nor does this valve have a manual override to open it. You much apply power to it. It does operate with between 9VDC and 24VDC so you could probably open it with a 9VDC battery if need be in an emergency. A small 12VDC gel battery which is maintained by a small battery maintainer solar panel could also be used along with a manual switch to apply the DC power if power is lost to the wall outlet for the power pack. Then manual operation of the valve could be possible without the home automation or outlet power working.

I've had about 5 of these pumping antifreeze for years. Thousands and thousands of gallons without fail. This will be the first replacement, and it isn't really even the fault of the valve. They have an issue with water intrusion if used in open air, it may take 5 years but it will happen. Solution? Drill a tint hole under the motor to allow any water to escape. Also, seal the top with a tiny bead of RTV. If you do that there is no reason this valve left outside, shouldn't last 10yrs+.

I purchased several of these 3/4" inch valves in stainless steel. I've worked with US Solid previously, I have two pumps from back in 2019 that still works flawlessly. Out of the valves I received in January 2021, two have malfunctioned after only between 50-70 cycles.. Out of curiosity, I opened the valve cover and found that most the gears inside it are plastic, and not the same plastics as in my older pump. The plastic in my new pumps seem like poorly 3D printed gears, which are almost completely worn out already. I assume that US Solid purchases valves from China for ODM marketing, which means they only slap their own sticker own it and sell it to consumer. This is fairly common practice and usually works quite well. But in this case, they have probably received sub-par valves which has ended in consumer hands. US Solid was quick to rectify this mistake and have given me full return for the valves. If you are in the market for valves, I advice you to buy directly from China(AliExpress) as valves like these go for US10-20. A CWX-25S is the equivalent valve, with manual override and sight glass and it goes for about 22USD plus shipping. Still, I have to praise US Solid's customer service, they were courtious and quick to respond.

Muy bue o y practico artículo y muy buena calidad

I bought this valve a week ago. After connect with pipe. It worked well. However, I found the water leak and have changed the fitting 3 times. I also used the fitting which work well with others valve. But the water still leaking. I hope the maker have a look to this problem and give me an advice. Thank you!

Very good

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

Very fast shipping from the US to Canada, received in a few days. Works great, have it hooked up to the main line Inside going to my underground sprinklers, so water pressure is not always on the outside zone valves. It's hooked up to the Master Valve out or pump 24 volt AC on the controller, When any zone is called for watering, it will open the Main motorized Ball Valve.
