has anyone used this solenoid?

Found this little gem on amazon for $11

It was labeled as a "pneumatic" and has an led indicator. Description mentions 0-150psi operating pressure.

I have a regulator and if this works then it will be an el cheapo solution for me

I haven't used it, but be warned that the units with LEDs sometimes get hot. I know LEDs 'run cool', but the electronics to make it all function do build up heat. I can't remember why this was an issue, but hot solenoids are not desirable from what I recall.

Does it have a power supply?

Here is a cut sheet on the valve.

Seams like a good solution, can't beat the price!

Thanks for the link Maryland.
Free, it doesn't come with the cord. I'll cut an end off of a computer power supply cord and wire it in, the terminals are right under the clear cap. Thanks for the led warning, I guess its due to the LED resistor heating up? I might disconnect the LED and try both ways.

I'll be back to report after its up and runnin.

That pilot LED won't make the coil hot.
Just feel the wiring cover where the LED is, it may not be warm at all.
I have never had a pilot LED melt the plastic wiring cover.

I'm just passing on rumors as something to research. I don't remember off the top of my head, but while researching solenoids and regulator builds, I stumbled upon something loosely coinciding with what I had previously mentioned.

Hooked this up about 24 hours ago, Also purchased a cheap needle valve from amazon for about $5 shipped. Both work excellent! the solenoid turned on and off and hold pressure at about 10psi, I touched it at the end of the day and it was slightly warm, the needle valve allows me to adjust from wide open to about 1 bubble every 10 seconds, and stayed true all day.

Total spent was about $16

SMC is a good company I have bought a lot of stuff from them as far as air connectors go usually the pneumatic stuff is not el cheap-o there not a high end company but I would say middle of the road defiantly I usually buy 5 way air valves every thing in 1/8 or 1/4 1 5way is about $50

Does it have a power supply?

Heat from a solenoid will warm up the metering valve and could cause a change in bubble count. (thermal expansion)

The solenoid should not get very warm as it's only 3 watt. The Burkert 6011 that's used a lot is 4 watt.

Update:
The solenoid has been running for a week now and has no issues or leaks.
It gets slightly warm but not much

Worth the $11 in my opinion, we'll see how long it survives.
