A valve for controlling the flow of fluid through a flow path, which valve comprises a housing (4) defining a flow path (5) and having two indented portions (3) about the flow path, a poppet (2) mounted within each indented portion such that the internal end of each indented portion defines a seat (8) which provides a fluid tight seal when the associated poppet head is held against the seat, spring means (7) associated with each poppet for holding each poppet against each seat, a rigid moveable member (9) associated with each poppet and adapted to alter the orientation of the associated poppet relative to its seat and thereby seal or unseal the flow path around the poppet, and actuating means (10) for moving each movable member; and inflator apparatus incorporating at least one valve.
