I want to get a valve that is opened and closed instantly by an electric
current. It will be put on a pressurized garden hose. When I hit a button,
the valve will open instantly, and water will spray out the hose. When I
let off the button, the valve will close, and the water will shut off.

I'm trying to make a simple system to help break my dog of barking.

What is the name of this valve/actuator/device? And where might I find one?

Hey Steve,

A solenoid valve, and a constant pressure switch. For a cheap try,
get one off a scrap dishwasher or automatic clothes-washer, and a
door-bell or horn type button. If you buy new instead, all come in a
wide range of voltages.

You can scrounge a line-voltage operated one from an old washer or
dishwasher, or buy a low voltage one (eg. 24VAC) in the sprinkler
section of HD or whatever. The sprinkler ones should have more
convenient fittings on both sides. I think less than $15 US.

Note that both of these will give you reduced flow, especially the
dishwasher one. I have used the washing machine ones to rig watering
for new lawns and they were just barely adequate. Bob

The solenoid activated jet of water idea is fine provided Rover (or is
it Scooby in the USA?) obligingly stands in the line of fire whenever
you want to train him. Also, I guess that you wouldn't want to soak
the inside of the house, so you could only train him when he was
outside.
A more versatile solution is the radio controlled high pitched
electronic 'whistle' that you fit to a dog's collar for training
purposes. The sound's frequency is too high to be detected by humans,
but dogs hate it. You still get to press a button so you're in
control, you save water, save mess and you don't get your own (water)
back whenever your soggy pooch shakes himself dry whilst standing
beside you.
Hope this helps

These don't exist. All solenoid valves currently on the market
take some time to open, about a half a second. You need to
look into a negative causality valve, which will stop your
dog from barking before it's actuated.

I've seen some where a microphone on the device senses the dog's bark
and turns the "whistle" on for a brief blast.

The pilot valve could be controlled by a thiotimoline crystal.

Solenoid valve. Get from McMaster or any supplier of inground sprinkler
systems.

Tried that on my dog. There is a slight time delay from the time the
valve acuates until the pressure builds up sufficiently to get a good
spray going. The dog learned to bark, wait for the first little sounds
from the solenoid, high tail it for his dog house. After the first
couple of nights, he didn't even get wet. Bought a shock collar for
field traing, left it on all night, blipped the controller from my bed.
About 2 nights and no barking. (Except when the deer stroll by his dog
kennel!)

I have one of those Jim. It worked so well I didn't even get the dog.

Oh - instantly means within ms or maybe a second or more - due to reaction time
being the largest component.

An air gate could do that - you would want 12V low voltage. How about a yard
sprinkler valve and a transformer and a switch. Just have to put in adapters
to the hose.

Home garden sprinkler systems are actuated by banks of these systems.
They even have regular plumbing fittings attached. Available at local
hardware or plumbing supply stores.
