An alternative to solenoid operated valves is motorised valves as used on heating systems, usually mains voltage, they are usually spring loaded shut and open when supplied with mains power :

(also, yea, I realized after the fact that ball valves are either on or off, been a while since I had a hydraulics class)


No, a ball valve can be used to throttle flow anywhere from full off to full on and anywhere in between, just by the position of the handle/ball. A ball valve's main claim to fame is that it can be made to allow full flow restricted by only the piping size and line pressure. That is a 1/4" ball valve has a full 1/4" hole in the ball and therefore allows full potential flow in 1/4" piping systems. They tend to be the more expensive style of valve per size because of the precision machining required to make the ball and seat. Not sure if plastic ball values are common and if they carry a price premium also.

Oh? :/ Well cool...

I know just enough to have the DESIRE to make trouble/a mess, but not enough to actually do it :P

That might actually be exactly what I need, pretty cheap, does what I need, etc


Thanks everyone for your help, I'll continue to poke around, but once I see something I like, it's usually the one I get (I'm an impulse shopper, except I wait a while before buying, but STILL buy the same thing :P)

I'm trying to find a electrically actuated water valve for a project.. something I THINK like this here

http://www.amazon.com/Parker-Valve-4Z-B6LJ2-SSP-Stainless-Compression/dp/B001C13DJ6

But preferably cheaper, that's obviously for an industrial application

My question is: Does anyone know of any search terms I could try to find more residential oriented ones?


I can help you,electric actuated ball valve,USD22 per unit,used for residential appliaction,skype:amyzhang3000

Yes,you are correct,mini motorised ball valve can be perfect alternative to solenoid valves,if your application is home automation system,please contact me,I can also help you,USD22 per unit,CE Certificate mini motorised ball valve is absolutely your first choice.

Intermatic PAV215 for about $18.50 USD

And the spendy bit

Intermatic PE24VA for about $75.00 USD

The 24V actuator attaches to the valve, useful for Arduino Low Pressure Irrigation type projects, the standard Solenoid Servo Valves don't cut it on gravity flow unless you've got about 40' head pressure.

Why not just use a sprinkler system valve? They sell them at Home Depot and Lowes and work off of dc voltage. They come in 3/4 and 1" outlets. Just use adapters to make it the size you need.  I think the company is RainBird but I'm sure their are other companies as well. In the spring you can get them at the hardware stores for like $10.
Because he wants flow control and those pilot-operated valves only do on and off. They also need 24v to operate.
