Can this be used with 3/4" pipes by using 1" to 3/4" pvc reducer? i have 3/4" pvc inlet does it help using bigger valve?

1'' valve fine using 3/4 piping on exhaust side, try to feed with 1'' on supply side for the volume, if coming off 5/8 meter go thru shutoff valve and backflow with 1'' to feed valves, have fun, i would use 1'' on exhaust, then to smaller pipes if on irrigation

Will this valve work to supply drip irrigation emitters or is there a different valve for those?

It will work. Just make sure to buy the filter that is used for drip lines so the emitters don't get clogged up.

I am currently using 3/4 inch ball valves to change flow from one circuit to another. Will this valve have the same flow capacity as the ball valve?

The same or better-----I think my inlet's and outlets are 1"----you will have to use reducers to adapt 3/4 " pipe. Please note that these valves are solenoid operated valves----as used with many electric 'timer' systems. I've found these solenoid valves to be trouble free over the many years that I've used them.

I have a rainbird controller with 25.5v is it compatible with those valves?

Yes. Believe the valve is rated 24 volts +or- . Be careful not to over tighten threads !

Good price, great product

This a great product. Just be careful if you use it with an orbit ground box. With 6 of them it's extremely tight
