Have you ever wanted to control the flow of a liquid using your computer or microcontroller, but didn't know how? Well, here's how: The 12V solenoid controlled fluid valve. Simply connect a fluid source to the 3/4" threaded inlet and it will interrupt the flow until 12V is applied to the fast-on connectors on the solenoid.
Note: This is not a gravity-feed solenoid. This means that you will need enough water pressure to fully open the valve. Check the datasheet below for exact details. It operates at a minimum of around 3 PSI, allowing around 3 L/min of flow. Although the datasheet shows the valve working at 220 VAC, it's actually 12 VDC. Our 350 GPH pump does not have enough pressure for this valve. A garden hose or other pressurized system should work just fine.
This skill concerns mechanical and robotics knowledge. You may need to know how mechanical parts interact, how motors work, or how to use motor drivers and controllers.
Skill Level: Noob - You will be required to put together a robotics kit. Necessary parts are included and steps will be easy to follow. You also might encounter basic robotics components like bearings, mounts, or other hardware and need a general idea of how it goes together.

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.
Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

I originally purchased this item for my hydroponics garden. Tests show the valve only works while under water pressure, kind of a safety feature. Then I though about a fountain display I wanted to build. I just purchased 8, 1/4" direct stream water nozzles. Besides interfacing this valve to standard pipe is the creation or purchase of a 12 DC, 8 channel control box.
There is many possibilities and uses for this product. Still wish for a low pressure valve for my hydroponics.

It works well for it's purpose; quick reaction times.
If you use this in a home garden setup, I recommend getting PVC adaptors to take the threads from pipe style to garden hose style.
I would recommend using blade connectors instead of soldering to the connection tabs; I had a hard time getting the solder to stick properly.
This is just what I needed thanks for all the spec on it that helped a lot.
Unlike other sellers this is advertised correctly; customer service quickly responded to a question - this is a normally closed valve. Was able to fit connectors on to run power leads; connection with garden hose water source pretty solid. Overall this valve works quite well.
I ran this off a garden hose with ample pressure to the garden irrigation I've set up, off of a 12v 3.3amp PSU.
For the first 30 seconds or so after switching the valve on, the pressure is about 80% of what it was before the solenoid was installed. After those thirty seconds, the pressure drops dramatically to about 30%, and all the sprinklers and sprayers just start spurting little puddles. If the solenoid is switched off and then on again, the pressure is good for another 30 seconds. I'm assuming it's because my hose is probably running at around 0.3 Mpa, and my flow rate is supposed to be around 22 lpm. This solenoid's data sheet (well, the 1/2" version listed anyways) says it needs 0.8 Mpa to reach 35 lpm. Unfortunately 0.8 Mpa would probably explode most of the 1/4" irrigation plugs.
Also, the solenoid was hot to touch after my initial tests (about 10 minutes of use).
If flow rate/pressure stability/lengthy use is your goal, this doesn't cut it. For quick fun hobby applications, it should work great.
Hmmm, this isn't behavior we've seen with this unit before. It sounds like you may have received a faulty unit. We're sending you out a new one, and hopefully that will fix the problems you're seeing.
