I use rainbird sprinkler valves which are commonly available in 3/4". I use two 3/4x1/2 threaded bushings and two 1/2" MPT to 1/4" QC fittings from Home Depot to plumb the valve into the RO line. The solenoid is 24VAC so you'll need an adapter which is sometimes the hardest thing to find. You can use thermostat transformer which are typically 24VAC or you may get lucky at Princess Auto or The Source. You can also order them online pretty easily from digikey or many other places.
