I apologize if this has been asked before or if I'm asking in the wrong place.
I am looking to build a controller for a sprinkler valve. I want to use a 5V microprocessor to run the valve. I have pretty much decided to use a Triac instead of a relay.
1. Any reason I shouldn't do this?
The specifications for the sprinkler valve are as follows...
24 VAC
Inrush current .35 Amps
Holding current .23 Amps
I'm considering using the following Triac...

Model LX807
2. Will this work for this application?
3. Do I need an Optocoupler (The data sheet seems to imply that it can be driven directly from the microprocessor.)?
4. Can you explain the quadrants to me?
I thought that if you wanted the full wave, you needed to have the gate driven with a matching wave. However, this seems to indicate that you must have a matching current but not a matching voltage. The voltage can be a constant 1.3 Volts DC. Is this correct?
Any help understanding this would be greatly appreciated.
