It's common for those hose barbs to be adapters that are threaded into an 
NPT connector. You should probably check to see if you can just unscrew the 
barb before returning the whole unit.

I've never seen a powered regulator. Normally the regulators are basically 
just spring-loaded valve mechanisms (yes I am oversimplifying a bit :-), 
and they don't require any power except for that provided by the pressure 
of the gas. If you have a solenoid valve than *that* would need power, and 
would also need a controller if you want to make use of it.
