Definately, you should do this regardless. Adding valve shutoffs to the recirculation loop and return line will give you both the ability to fine tune your flow rate to the display, and/or shut off the sump from the display completely. Shutting off the return is helpful when working in the sump. that way anythiing you stir up in the sump, wont end up in the display.
I have a friend who discovered the need for this feature after a near catastrophic event. During a routine macro algae harvest, the DSB in his fuge was disturbed when he moved some algaes that had begun to root in the sand. The gasses released into the water traveled into his display and all of his fish and inverts suffered a temporary paralasis. All but 1 fish survived, but in SW, 1 fish could be a big loss..
