TL;DR
A line pressure regulator is a gas valve installed partway through a piping system to step elevated pressure, commonly 2 psi, down to the half-psi range that household appliances accept. It is the defining component of 2-psi systems, which use smaller-diameter pipe to feed long runs in large homes, and it must be vented or listed for vent-limited indoor use.
