*The Marshall Excelsior-199 is an exact clone of a model 99 pilot-operated regulator
The regulator’s high accuracy keeps constant inlet pressures to downstream equipment by accurately controlling distribution system pressures at widely varying flow rates and supply pressures. The device also eliminates the need for pressure-compensating meters by holding a steady pressure to the meter inlet.
