A modular style regulator with built-in pressure gauge, series ARG offers an optional, built-in backflow mechanism which enables reliable discharge of air pressure from outlet to inlet.  The mounting angle of the pressure gauge is selectable depending on the piping direction, and with the anti-revolving mechanism (PAT.PEND.), the pressure gauge will not be revolved even after the handle
