AOMAG® 1/4" DC 24V 2 Way Normally Closed Pneumatic Aluminum Electric Solenoid Air Valve

Used this for a DIY sprayer project. Worked perfect.

Product was exactly as described

These are good valves for the price. I used these to build a remote controlled braking system for a vehicle for crash testing purposes. The valve is energized remotely and then allows air flow from a storage tank to a shock mounted to the brake pedal. Has enough flow and pressure to fully move the shock, around a 5 in stroke, and maintain pressure on the pedal. Survived a 40 mile per hour impact and is still working fine. Very pleasantly surprised by the performance of this valve.

Nice little solenoid with precision threads. Has held up well regulating 40-100psi from my air compressor for extended periods. Would recommend for the price!8/27/2018 - After a couple weeks of use, the plastic housing is slightly leaking now. I've unscrewed and reattached/teflon'd this solenoid twice now and it's threads are still in good shape.

Installed 2 of these in my car to actuate a pneumatic exhaust cutout. Knowing so little about inductive loads at the time of purchase I was surprised when it stalled my car upon releasing power. I didn't know it at the time but the collapse of the magnetic field in an inductive load sends a NASTY voltage spike into your electrical system. I added a diode backwards between the positive and negative leads when rewiring them and I never saw the problem again. They have worked as expected this entire time with absolutely no issues.

switching this at insane speeds under high pressure and it hasn't failed me yet

Installed and it slowly leaks air

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.

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

Great quality, recommend it!

Medidas contenidas buen funcionamientoCoge algo de temperatura perdonada preocupante

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

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.
