A fluid valve (3) for incorporation in a container (1) for storing a fluid under pressure and arranged for charging the container therethrough with, and dispensing therethrough from the container, a pressurized fluid, has a chamber (4) having at one end an inlet (15) and at the other end an outlet (9) for the fluid; a valve piston (5) sealingly guided and movable within the chamber (4); and a valve member (10) which is also movable within the chamber (4); the piston (5) having a valve seat (7) and the valve piston having a valve seal (12) arranged for sealingly cooperating with the seat (7) which is disposed towards the inlet (15). A passageway (8) leads from the seat (7) to the outlet (9). The valve member (10) is biased by a spring (13) against the seat (7) to close the passageway (8), and has an extension (11) passing through the passageway (8) and the outlet (9). The construction of the valve is such as to permit duly authorized operators to refill the container while tending to prevent unauthorized operators from doing so.
