Abstract
A pressure reduction valve 2 includes a piston 12, a pressure regulating sub-chamber 50 and a movable means, preferably in the form of a second piston 12', which is activated by a filling nozzle 70 to prevent the flow of fluid between an inlet 8 and the regulating sub-chamber 50 thereby to allow the flow of fluid through the valve between an outlet 10 and an inlet 8. This allows a cylinder to be filled whilst the pressure reduction valve 2 is in situ.
