I like the
Irritrol 2711APR for 3/4 inch and the 2713APR for 1 inch pipe. As a side note, make sure you get the APR and not the DPR.

Keep in mind the distance between the two threaded ports will be different between the valves you have now and the Irritrol 2700 series. You might have to redo them. Well you will have to redo them.

On the link I posted it says that the flow control and bleeder screw might break if the valves are left in the sunlight for too long. You wont have to worry about that with these two models. With that said, sunlight is bad for all valves in my opinion.
