Works great - BUT be aware that there are a few caveats...

This is verifiably a direct acting solenoid valve, meaning that all movement of the diaphragm is from the energized coil itself. It does NOT require a minimum operating pressure to fully open, which is a much more common design to find. However, that capability comes at a price: operation requires a very powerful coil. But powerful coils draw high CURRENTS and cannot sustain that full current for more than very short periods without OVERHEATING. If your application only requires that the valve be energized for 5 seconds every few minutes and NO MORE, you'll probably be fine using it as-is. Otherwise this MUST be driven using some form of active current/voltage control, i.e. PWM. The resistance of the coil for the 1/2" 12 VDC version measures 5.5 ohms, drawing just over two amps at 12 volts, dissipating 26 watts of heat, which is quite a lot in such a small space. The secret to success is understanding that full power is only needed for a brief time to initially open the valve but a MUCH smaller current will HOLD the valve open. In my case I've got an Arduino Mega driving an H-bridge motor controller that actually powers the coil. To open, full current is supplied for about 100 milliseconds after which it drops to a fraction of that by switching to PWM with around a 30% duty cycle to maintainin the open position. Using this scheme I've yet to have a failure to open or to stay open and the body of the valve never goes above ambient even after hours of being powered. The only other things to be aware of are that it makes a VERY loud click when activated and the threads are NOT NPT, they are not tapered - so expect to use a LOT of sealing tape if using conventional pipe fittings.

Super solid. Works on 12V DC. Works perfectly.

Great valve. I love that I can power it with 12V DC. It doesn’t like the cold that much, but that’s alright. I actually had a heated hose connected to it and the heat transfers which keeps it from freezing. Wonderful product works great. Thank you ☺️🙏

Worth the money

These are a very good value for your money, they don't leak and looks as if they will last a very long time. Worth the money

Nice heavy valve

Nice heavy valve, works as expected and is perfect for the project I am working on.

Great value

Better than battery waterer if used with a timer. Great value

Great price for an excellent product

Good deal, used to put airbags on my truck.

Completo

Justo loque estaba buscando

Works perfect

This works perfect for what i used it for

Good price!!!!

I used solenoid for a hollween prop. It work great. Good price for what I use it for.
