The device for controlling fluid, particularly a pressure-reducing device for a gaseous fluid, according to the invention comprises a valve 10 interacting with a seat 12, an actuating means acting on the valve in the direction for opening it by means of a membrane 16 and a pusher 11 interposed between the membrane and the valve, one first end of the pusher bearing like a ball joint against the bottom of the concave part 19 at the centre of the membrane and the second end of the pusher interacting by interlocking with radial clearance with the valve, means for guiding the valve, and a closure spring 7 consisting of a compression spring one end of which bears against a fixed support surface and the second end of which acts on the valve counter to the actuating means. According to the invention, the guide means consist solely of the closure spring 7 which is a spring which high lateral stability which is not guided and is centred coaxially with the seat of the valve solely at its first end. <IMAGE>
