Abstract

A system includes a first pressure-adjusting device positioned in a first line and a second pressure-adjusting device positioned in a second line. The first pressure-adjusting device is actuated solely via a first pneumatic signal output from a first pilot valve to control a downstream pressure in the first line. The second pressure-adjusting device is actuated via the first pneumatic signal in a first mode of operation, and is actuated via a second pneumatic signal output from a second pilot valve in a second mode of operation to control a downstream pressure in the second line.

Abstract

A gas pressure regulator (1) comprises a central body (2) having a first, gas inlet pipe (3) and a second, gas outlet pipe (4); a shutter (5) housed at least partially in the central body (2) and mobile to adjust the opening of a section (6) for the passage of the gas between a position (B) in which the section (6) is fully open and a position (A) in which the section (6) is closed; a silencing device (7) located in the central body (2) at the passage section (6), for reducing the noise created by the passage of the gas; and means (11) for fastening the silencing device to the central body (2). The silencing device (7) comprises a cylindrical perforated plate (9) to allow the passage of the gas.
