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
valve to regulate the CO2 from a DIY yeast bottle....?

As far as I know you don't regulate the output from a DIY bottle - you could
have a potential bomb on your hands if you tried. Needle valves are for
pressurised systems only. Also I suspect a std airline valve would leak CO2
like a sieve - as does silicone Airline tubing (!)
