Again, it would require a computer, but that could be anywhere in the house as the home automation gizmos use power line and/or RF communication.
This is exactly what I did at some point before I had a stirplate. I think I might have even posted on the forum here about doing it.

Of course I already had the X10 gear and PC with software on it

HAHAHA! With such a fricken judicious use of consonants, what do you expect? I work for a German company and have to deal with the language every single day. Consonants must be dang cheap over there!

Kai, I don't see why you couldn't do it cheaply with a couple of timing relays. One relay with a delay on and the other with a delay off. Let me see if I can make this explanation as convoluted as possible..... Relay with a "time off delay" (Relay A), one set of NO contacts powering your valve and a set of NC contacts powering the coil of the other relay. The "other" relay is a "time on delay" (Relay B). A set of NO contacts power the first relay coil.
Adjust "Relay B" to 5 minutes, when the time is up it will close the contacts, thereby powering the coil of "Relay A" and start it's timing cycle. Once relay A (set to 1 min) completes it's cycle, it will switch and close the...... wait a minute. $hit, I am getting into an endless loop here......
I need to draw this out first. Give me a bit.

OK, let's see if I can explain this. Sorry for the crappy drawing, but I just threw it together.
When you apply power, Timer A begins timing. After 5 minutes, it switches "on" and stays on. That will turn on your valve and start the Timer B. After 1 minute, Timer B will change states and both timers will switch off instantaneously, allowing the NC contact "B" to close and start the timing cycle of Timer A again. Both timers are "ON" delay, meaning they will time for their set time before switching....
Is this clear as mud?

I do too.
My thought, besides tradition is why the hell should I pay for something to keep the foaming action of my yeast down when I can just get a bigger fermenter?

Sure. I ferment my 10 gal batches in one of these and have never had a blowoff yet!

I have just what you are looking for. I use mine to run a mister for my houseplants. I have it set to go off for 5 min. about every 1.5 hours during the day. It is digital. I can't remember the brand. I'll check tonight at home. I'd swore I bought it at Lowes, but I don't see it on their website.

I did find this one though at $23

How did you progam this? Did you program the countdown timer or did you program tha actual time of the day when it should go on/off?
