electronic valve shower, do you have an idea???

[jeffjavier]

hi,

do you have an idea on building up an electronic shower valve in which it can be controlled using a switch, this is my problem in my plants watering system.

Hi Jeff,

Do you just need a circuit to open and shut an electric valve or should there be some kind of sensor to control the valve?

 

[Yevgenip]

About the mechanical bit, you should use eather two electromagnets or a motor to close and open the valve.

Hmmmm....I'm thinking that a simple, 24VDC, solenoid-operated, irrigation (sprinkler) valve body and head would be the exact thing you're looking for.

After some thought, you might also get away with using a solenoid-controlled valve for a refrigerator/freezer icemaker sub-assembly...probably quite a bit cheaper, although it will be operated by mains voltage.
In that case, you could swap-out the coil for a low-voltage coil, or use a SSR to switch the mains voltage to the solenoid coil.

You can control a mains powered valve via a small relay, or a triac and an optoisolator.
There are some nice solenoid valves to be scavenged in scraped washing machines and dishwashers .

In that vein, this type of thing is probably what you're after:

Yea, that

 

[EnigmaOne]

Yup, but the best way to get one is from the junkyard...much more economical that way.

If you think about it, people can live their whole lifes in junkyards without ever being hungry or poor.

If you're still interested, a good place to find solenoid valves is a washing machine. I dismantled one that someone threw away (it was in perfect condition, just old). I took several usefull parts out of it.

What a lousy life that would be. What about internet?
I guess they could get shelter in a discarded washing machine. ;D

Hi

from:audioguru I guess they could get shelter in a discarded washing machine.

better yet, join lots together to make a condo, rent it out (internet now possible)

Hey it's saturday, wind-down time  ;D

as long as your junk yard is near a building or something that has wi-fi then you are set... free internet and cheap property tax.  ;D
