Replace Soda Regulator Guage for Beer?

I just got a soda regulator with two low pressure gauges (0-160 psi) and a high pressure gauge. Can I just simply simply unscrew and replace the 0-160 psi gauges with a 0-60 psi gauge to more accurately set my co2 levels?


Also, the regulator didn't come with shutoff valves, which I believe to be fairly important......along the same lines of above, can I just screw on gas shutoff valves to the low pressure outputs?

Thanks (this is my first real question post!)

Yes, also consider 0-30 psi gauges.

Yes, you'll find them useful and consider installing check valves as well.
