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?
