A Simple 120V servos?

Hi all. I hope this is the proper forum for my question.

I have a simple motion detector. When it detects motion, it turn on a 120 volt switch for either 30 sec, 1 min, 5 min, or 10 minutes.
I also have an air line with an on/off ball valve.
Here is the valve I'm talking about:
http://www.surpluscenter.com/item.asp?i ... atname=air

What i need is a servo i can plug into the motion detector. When the power is turned on, the servo turns on the valve and when the power is switched off, the servo closes the valve back.
Or i dont even need the servo to turn off the valve, a simple spring or bungy cord could do that when the servo stops pulling the valve.

The servo needs not be very strong because the valve can be turned by hand with two fingers. The valve has a 90 degree rotation between on and off.

What kind of servo would do this?
And where could i find such servo?

Thanx for your help!

Cheers,
PepeLapiu

Hii

keep in mind that when using a servo also need servo controler card (an any case if the servo its a pwm type or Daisy Chain Serial type ) and make a program to send the commands to the servo controller card

a simpler and cheaper way to do what you need is to use an electro valve or solenoid
may be you can consider use an electro valve, thats is use in automatization of fluids, such as washing, where to put your hands under the faucet, water comes out.

the price depends on the size and voltage to the solenoid works.

if use the electrovalve connect the output of the dc conver at electrovalve and the wires of alimentacion of dc converter at to switch that you have.


In the next links you find some examples of this.
