Valve turns on and off very quickly

Recently one of the stations on my sprinkler system started acting up, the valve turns on, but then begins turning on and off quickly (at least once per second). I've tried reducing the flow through the valve, which doesn't seem to do anything. The rest of the stations are working fine. I recently replaced the diaphragm on this valve, as it was leaking, but that was several weeks ago, and the problem just started a couple of days ago.

I have my sprinklers set to run around 3 AM, and the first time this happened, it woke everybody up, as you could hear the valve turning on and off throughout the whole house.

Thanks in advance for the help and assistance!!

That sounds like the controller to me. Try moving the wire to a different slot on the controller and see if that fixes it.
RainDial's do that.
If it still happens I'd swap out the solenoid and see what happens.

Try opening the manual bleed when it does that. If the banging stops, close the bleed and shut it off at the controller. Try it a few more times to see if it has fixed the problem. If not, you might need a new solenoid.
