Is there anyone who doesnt use a needle valve for CO2 injection. I
wanted to know if its possible to just use a standard aquarium gang

Needle valves are used with compress-gas CO2 systems.

Do NOT!!!!!! attempt to use any type of valve to restrict the flow on
a YEAST system. The plastic and/or glass container the yeast
mixture is in can easily explode.

If you need to reduce the amount of CO2 from a yeast system, the best
method is to use a powerhead to create some surface aeration, which
will release some of the CO2 gas.
