AOMAG® Solenoid Air Valve AC 110V 1/8inch 2 Way Normally Closed Pneumatic Aluminum Electric Solenoid Valve

Quality products and fast shipping

The seller did ship fast and technically the item works. The valve does not let enough volume of air through to operate an air horn though. I was trying to replace a Grover solenoid that had the same sized ports but sadly, the horn squeaks instead of honks. Not much money to waste really, it was worth a shot.

If you install backwards the valve will leakBe sure to install correctly

I took my chances on this valve because similar ones I looked at had reviews that said they over-heated and this one didn't . However, this model operated on 12v DC gets too hot to touch after 10 minutes. I'm sure it would catch on fire before an hour passed. That's unfortunate because I'm building a circuit that controls this to heat my greenhouse. I figure on a cold morning following a cold night this solenoid valve might have to be on for an hour before the temperature gets up. I thought I was going to have to order a more expensive one that used more coils of copper wire in the solenoid, but first tried lashing a large aluminum heat sink to it. And SURPRISE, that worked. It lasted 90 minutes and did not get too hot to touch. So that will work as long as you have a spare heat sink. As for how long it will last or how well it seals, I won't know until I start using it.

The solenoid that came with my horns was 12/24 volts... but it didn't actuate with less than 13+ vdc... so if the engine was off... no horn.. this one I pushed down to 10vdc and still functions. So it did fix my problem.I'm going to get another one to shove more air to the horns and in case one fails the other one remains.The horns have a real-life use... My kids go riding their quads and I call them back with the train sound... it carries over a mile with 90psi. I would recommend I would buy again.

Others have mentioned that the threads on these aren't necessarily fully formed (knew that when I ordered), but on the 1/8" version I received, one of the two wasn't even fixable with a tap because somehow the existing threads were off center on the bore (one wall was smooth). I needed to get something running so I ended up JB-welding a pipe nipple into the opening to make it usable. The valves seem to work OK, so if you're willing to put up with probably tapping and possibly taking more drastic action to hook them up, go for it.UPDATE 10/25/2021 - The supplier contacted me to let me know they've changed manufacturers for the valve because of the reported quality issues. I've updated this review and added a star for the supplier actually reading the customer reviews and trying to compensate for the issue. Since I have no way of confirming the change in manufacturer I feel I have to leave this review in place as fair warning, but note that the supplier is willing to work with you. Pay attention to reviews after this date to see if QA reports improve, and recognize that there's almost always an effort/cost trade to be made in buying products at this relatively low price point.

Failed to operate after 2 months

Works great

Très bon produit . Un peu lourd . Mais ça fait bien le job .

Used on my sawmill for blade lube control, go through 1/4 of the lube I use to

Works well

Thought this would work for an air horn. Sure it’s 1/4inch threads but the hole for the valve is tiny. It’s a great little unit and it works great but the air flow is seriously restricted.

Solenoid deployed in a hydroponics setup to control foggers.Worked well for about 6 weeks, then something happened to the valve: I can hear the tick sound as the solenoid goes on and off but the valve passes only a trickle of water or none at all.Quite disappointing, given the high number of favourable reviews.I will give it an interim 2 stars, pending the response of the supplier.To be updated soon.
