Summary:A gas pressure control valve having a valve body (11, 12) with a gas inlet (25) and a gas outlet (58) is described. An inner cap (40) is provided bounding in part a chamber (47) within the valve body (11,12) in communication with the gas inlet (25). The valve body (11, 12) contains a spring loaded piston (32, 33) comprising a piston head (32) and a piston rod (33). The piston rod (33) includes a conduit (50) providing communication between the chamber (47) bounded in part by the inner cap (40) and a chamber (45) adjacent the piston head (32) and the gas outlet (58). The piston (32, 33) is operable to move between a closed configuration in which the piston rod (33) prevents communication between the gas inlet (25) and the chamber (47) bounded in part by the inner cap (40) and an open configuration in which the piston rod (33) permits communication between the gas inlet (40) and the chamber (47) bounded in part by the inner cap (40). The piston head (32) is in a sealing engagement with the valve body (11, 12) v
