When seeing this system for the first time I thought the only advantage to it is the second pipe as a contingency if the first gets clogged. I didn't understand the silencing aspect of controlling the return flow from the first pipe.
So I did go out today and get a 2 " ball valve to install tommorow on the main return pipe to the sump. Based on fkshiu's comments this isn't optimal a gate valve is better?

Uh ya.. no valve on main drain means no herbie for you!
Although a ball valve
can work, in the end it will just drive you insane in the membrane. So do yourself a favour and ditch the ball valve and install a gate valve as previously suggested. Otherwise you'll be back here asking why it is so difficult to control the water level of your Herbie
You didn't mention it but I still think your main drain pipe is a tad too high :-)
Looks something like this..
Notice how much higher the emergency pipe is from the main pipe. On yours, it looks like by the time the water clears the main pipe (for silencing), the water level will have reached the emergency pipe and thus will make noise in the pipe and from splashing in the sump. If you're monkeying with the plumping mind as well fix the pipes. As suggested before you could also remove the main pipe completely.
Gate valve on main drain..
