Abstract
A regulator installation, for controlling the pressure and/or flow of gas in a gas transmission or distribution system, comprising a compact module (10) having an inlet (32) and an outlet (33) adapted to be fitted in a pipeline (1) and containing within its outer shell (21,22,23) a removable assembly secured by locking means (29,30) and which carries the essential elements (2 to 9 and 43 to 45) of the regulator installation such that the gas flow path from the inlet (32) passes through the elements (2 to 5) to the outlet (33). The shell is provided with a removable cover (23) for gaining access to the control elements (6 to 9 and 43 to 45) and to the locking means (30) for enabling the assembly (31) to be removed for servicing and replacement. FIG. 2 is suggested as the drawing to accompany the Abstract.
