Abstract
A system for adjusting pressure of a gas includes: a first shutter unit for causing a pressure drop in the gas, from a supply pressure to a delivery pressure; a pilot unit for providing a pilot pressure depending on the difference between the delivery pressure and a predefined setting pressure; a first drive unit operated by the pilot pressure to reduce the opening of the first shutter unit when the delivery pressure exceeds the setting pressure, and vice versa; a second shutter unit in series with the first shutter unit can assume a closed configuration; a second drive unit operated by the pilot pressure to reduce the opening of the second shutter unit when the delivery pressure exceeds the setting pressure, and vice versa. When the first shutter unit is open the opening of the second shutter unit causes a pressure drop smaller than the pressure drop by the first shutter unit.
