U.S. SolidMotorized Ball Valve- 1/2inches Brass Ball Valve with Full Port, 9-24V DC and 2 Wire Reverse Polarity by U.S. Solid

I built a water tank level controller using this valve in 1/2" and it works perfectly. I used a Dual H-Bridge driver for the positive and negative voltages to open and close the valve with an Arduino Nano to provide the logic. The Nano provides +5VDC signal which isn't enough to operate the valve and won't allow the valve to operate in the opposite direction by itself. To get to 12 volts and have positive and negative power for opening and closing the valve, I used the L298N Dual H-Bridge driver with two pins on the Nano as the open/close signals. There is probably a better method to control the valve but all of this stuff is readily available on Amazon for cheap and it works pretty good together for a long time, still working six months later...

This is what I had hoped. The ball valve has a secure seal, and will work with air or water, I tested it with air before install in water system, and it stayed sealed even at 165psi on air. Water system is running at only 72psi from regulator, and holds without even a drip thru. I use regular small 12v 4ah battery on my setup, since zero power is used after cycle completes, you only need to setup with DPDT toggle switch to open and close valve. Simple but elegant idea, saves having to cut power after cycle end. I can not figure why someone would choose 9 volt, to operate the valve, since using a nine volt battery wouldn’t have enough available current to be reliable, but since it was brought up, I applied 9v from bench power supply to the motor valve and the one I got, did in fact cycle both full close and full open. The speed was very slow about 5 second to cycle, compared to approximately 3 seconds on 12 volt. That top limit of 24 volt, is the handiest feature, you can run the valve even if your battery charger is active, without having to regulate the voltage to valve. My setup is solar, and the valve draws no power when full cycle, so basically you just need to reverse the power with DPDT switch labeled ON OFF. My valve is about 50 feet from where the control is located, and I used 16/2 direct burial cable to connect between, and the motorized ball valve, works flawless.There are many ways that this valve could activate other than direct control, search for latching relays, they still make them. In my particular setup, I just needed to be able to turn the valve on or off, without having to go to the valve, (and get either cold or wet in the process) This valve solved what I needed. It is a great product.

Works a treat. Used to remotely open and shut a grey water outlet on a motor home.

Full port stainless steel internal. But the control board needs to go away. Similar brass valves exist, with better design for longevity of the electrical parts. Not happy that it says U.S. on the label because it's misleading, made in China.

Estaba bula de bola es muy buena para la plomería de sistema hidroponía

Very surprised by the quality of this valve. Impressed with the switching power supply imbedded within which allows a very large range of DC voltage to operate. Even works with single diode rectified 24VAC without humming or buzzing. Very nicely designed. It also operated at the same speed opening or closing regardless of the input voltage from the low end to the upper limit. I am very happy with it. Also not that this valve stays inplace if power is removed. It also cuts of the power once it is in its end position, only drawing power when moving. Simply reverse the voltage and the valve operates in the opposite direction untile it hits that limit the shuts off the current. No heating or noise after it is completed its motion. Takes about 10 seconds to open or close.

Purchase from Amazon that said after 60 days we should contact Supplier US Solid at their phone number. Phone answered with voice mail that said they are not accepting voice phone support, to send email. I sent an email explaining the problem, giving my email address and phone number, and requesting a replacement actuator. I have not received any reply 4 days later.

Originally I bought only one to see how well they work. I have three now. Two control water to some ornamental plants and one a misting system on my A/C. Originally bought one just to see how well they worked. They work fine, I haven't had any issues with them. I believe I bought the first one about three years ago, the third about a year and a half. No issues with them at all. The A/C one is controlled by the A/C Thermostat. A/C comes on that one opens, when it goes off, it closes. Has worked without fault for 2 Summers in California's very hot Central Valley.

Bon service en cas d’échange nécessaire.

Cumple perfectamente mis requerimientos, la casa que habito forzosamente tengo que subir al techo y escalar un cubo construido alrededor del tinaco para poder cerrar la válvula de paso del agua cada que se requiere una reparación o mantenimiento, y con esta válvula me evito toda esa molestia y riesgo de sufrir algún accidente.El modelo que me llegó requiere un interruptor de seis patas para poder invertir la corriente, yo lo conecté a una fuente de poder de 13 volts con 10 amperes que utilizo con un radio CB ya que el su uso que daré a la válvula (en mi caso) será esporádico. Con ese voltaje hace el recorrido de cierre/apertura en tan sólo 3 segundos.

Harika çalışıyor.

Elettrovalvola solida ben fatta già collaudata, molto adatta in quelle situazioni nelle quali l'apertura e la chiusura avvengono a intervalli lunghi in quanto non consuma corrente una volta raggiunta la posizione di apertura o di chiusura tanto che è possibile staccare l'alimentazione una volta ottenuta la posizione desiderata.

Nach Rücksendung eines anderen Fabrikats hat dieser Kugelhahn bis jetzt perfekt funktioniert.
