Abstract

A method and apparatus for controlling the fluid pressure of an inflatable stopping bag (1a, 1b) used to block the fluid flow through a fluid conduit, wherein the bag using a pressure regulator (25) which operates to regulate the pressure of the bag as a function of the instantaneous pressure in the pipe upstream of the stopping bag.
