<p>A flow apparatus 10 for a vessel storing fluid under pressure having a flow control valve 12 having an outlet aperture 16 and further including a valve seat 18 and a sealing member 20 for sealing against the seat 18 to close the outlet 16, the apparatus having an actuator 22 connected to the sealing member 20 for moving it between an open position and a closed position, characterised by an electrical switch 24 for controlling the supply of electrical current to one or more electrical components 40, sucha s a display, and wherein the switch is operably connected to the sealing member 20 to allow for the passage of current when the valve 12 is in a first position and to restrict the flow of current when the valve 12 is in a second position. Such an apparatus may be used to control the flow of gas from a gas bottle and to ensure that electricity is only supplied when needed, thus prolonging battery life and reducing maintenance.</p> |
