The invention is directed to a device (2) for regulating the pressure and/or flow of pressurized gas, comprising a body (4) with a gas inlet (6), a gas outlet (8) and a gas passage (10, 26) connecting the outlet (8) with the inlet (6), a gas shut-off device comprising a seat (22) in the passage (10) and a movable closure element (24) cooperating with said seat (22) and a piston (12) carrying the closure element (24) and delimiting with the body (4) a low pressure chamber (28) downstream of the shut-off device (22, 24). The body (4) comprises a first portion (41) with the seat (22) and the inlet (6) and a second portion (42) housing the piston (12) and delimiting the low pressure chamber (28). The second portion (42) is movable relative to the first portion (41) between a closed position, and an open position.
