I bought this ball valve for an air compressor. I kind of feel dumb asking but the directions are terrible. It is has a black and red wire coming from the valve. What should these go to?
That is absolutely right. A 3/4 inch valve going full open in less than 5 seconds will be wild.The noise will be incredible if that is going to open air
I am going to use this to turn air on/off to air lines in my shop. My compressor is a pretty common 60 gallon 220v compressor. I am planning to just run this off of one leg of the 220 for the compressor. I guess i'm still kind of confused though with just a red and black wire.....could I hook the two wires to each of the hot wires of the compressor? I know it shouldnt be with the compressor probably.....it will work though.What are you trying to accomplish with this valve....blow down or distribution piping isolation?
What electrical control hardware is on your compressor.....line voltage, lever-operated pressure switch or motor starter?
Did you buy the 240volt version or the dc power supply version as shown in the video?
What's the voltage of your compressor ?
It's a 240volt valve correct?
Take a pic of It's nameplate.
You don't mention the hardware controlling the compressor. Need that info.
If it is a 240v valve, you will ultimately wire it across both hots. If it is 120vac only, it will need a hot and neutral. (Can not use the ground wire as a neutral).
Just curious why a simple lever operated ball valve wont work ? thats all I have but to be honest with you it has probably only been used a couple of times in the 38 years I have been in business and that was if I needed to fix something on the lines.I am going to use this to turn air on/off to air lines in my shop.

I’m thinking the same thing.Just curious why a simple lever operated ball valve wont work ? thats all I have but to be honest with you it has probably only been used a couple of times in the 38 years I have been in business and that was if I needed to fix something on the lines.

I'm weird. I wont use the compressor that much....hoping with this, i can keep the air in the tank when its off with no effort.I’m thinking the same thing.![]()
And the video doesn't match the particular details of what is offered for sale. So w/o part in hand, you don't know what you are getting.The webpage for the valve has instructions and videos!

3/4" Motorized Ball Valve with Manual Function - 2 Wire Auto Return, S
INTRODUCTION Motorized ball valves are a vital piece of equipment in numerous applications. This model opens and closes in 3-5 seconds, and remains in its new position while expending almost no energy. This is a key difference between motorized ball valves and many solenoid valves. Most solenoid...ussolid.com
3rd time......What is the electrical hardware used on the compressor?I'm weird. I wont use the compressor that much....hoping with this, i can keep the air in the tank when its off with no effort.
2 N m Max Medium Pressure ?I also don't see pressure rating for that
Based on the description in the Amazon page and the OEM webpage and the info on the top of the valve, applying 240v across the wires will open the valve. So if you wire it so that it has power when the compressor has power, not just when the motor is running, you should be able to get air when the compressor is powered.I am going to use this to turn air on/off to air lines in my shop. My compressor is a pretty common 60 gallon 220v compressor. I am planning to just run this off of one leg of the 220 for the compressor.

Motorized ball valves are used very frequently in industry all of the time. Just not Amazon specials.I'm not sure that a motor controlled valve is ideal for air pressure, I also don't see pressure rating for that
Until you have parts in hand, the diagram above doesn't show a connection to ac. I wouldn't trust an Amazon description alone.
That's just the maximum output torque of the actuator.2 N m Max Medium Pressure ?
How much is “not that much” ?I wont use the compressor that much....hoping with this, i can keep the air in the tank when it’s off.
That was my fear, that there is both an ac and a DC version where the "ac version" may have required a dc power supply in-between ac source and actuator.If you go to the US Solid website, the page for that particular valve has schematics for the various configurations. Click on this link and scroll down: https://ussolid.com/products/u-s-so...dard-port-85-265-v-ac-2-wire-auto-return-html For 2 wire auto return, it shows the wire color doesn't matter, just hook up the two wires to AC.
Or get a motorized ball valve from a reputable manufacturer, not an Amazon special. I don't recall ever seeing a ball valve rated for only 145 psi, 600 cold working pressure is typical for a ball valve, in my experience, and they go up from there.That inexpensive powered valve might leak like the rest of your system (apparently) does. If you can’t fix the leaks, I would just install a high quality manual ball valve. More reliable.
Not that it means anything but US Solid is a brand name I've never heard of before.Or get a motorized ball valve from a reputable manufacturer, not an Amazon special.
You are seriously making this way more complicated than it needs to be. You wanted a picture of the valve. Op posted it. It says in black and blue "85-265V AC"! What more do you want? It's two wires. It's not that fn hard!That was my fear, that there is both an ac and a DC version where the "ac version" may have required a dc power supply in-between ac source and actuator.
So the ac version can directly connect to the 240vac per mfr explicit instructions.
Consistancy in documentation.......so you don't burn the controller up and then look like a dumb sh*t.You are seriously making this way more complicated than it needs to be. You wanted a picture of the valve. Op posted it. It says in black and blue "85-265V AC"! What more do you want? It's two wires. It's not that fn hard!




Pretty straight forward for that valve. Video link here: https://www.amazon.com/vdp/05602f1c0841473e8910c52f03103ee0?tag=atomicindus08-20
There are high voltage AC and low voltage AC/DC Versions of the same valves available. They are both two wire. Apply power, valves open, remove power, valve closes. Very first moment of the video says polarity does not matter on the AC valve. They work as described and there is zero need to overthink this. Sure the documentation may not match exactly due to variations in production wire colors. But if polarity does not mater and there are only two wires and it's AC - it's kind of hard to screw it up....So why show a power supply if this part is being sold as an AC application??
Notice the switch in the power supply ac cord.........different than the diagram.
Did you miss this pic from the OP of his valve?As long as you have an ac actuator.
I took my information from the U.S. Sold website: U.S. Solid Motorized Ball Valve- 3/4" Stainless Steel Electrical Ball Valve with Standard Port, 85-265 V AC, 2 Wire Auto ReturnIf you trust all Amazon descriptions , good for you.
They are a pretty good value for their price. It's not too hard to figure out the wiring if you spend a little time deciphering the Chinglish. Many times Chinese manufacturers try to make their instructions universally compatible. Unfortunately, it's usually not a very successful implementation.I've had a couple of these, they work well.
That's when it's time to take advantage of their generous return policy. It's about the only time I will return something - when the description is so poor as to make it unusable after receipt. Usually I won't buy something if it's that unclear of its suitability to my needs.I have bought random stuff from Amazon and details were wrong that made the item useless.
Thanks for closing the loop on this.Update….wired it up tonight. Works great!
