I'm really looking for something with 5V operation. There are commercial watering timers that use a 5/6V rotary valve and others that use a magnetically operated valve that requires just a short pulse of +ve voltage to operate and another of -ve voltage to close. The seem to use the water pressure through bleed holes to then maintain the current state
