A device for regulating pressure supplied to a railway pneumatic cylinder brake caliper via an upper solenoid valve for increasing pressure and a lower solenoid valve for relieving pressure, and including a pressure regulator configured to compare a first signal representative of the pressure measured in the caliper with a second signal representative of a reference pressure, control the opening of the upper solenoid valve when the value of the first signal is lower than that of the second signal, and on the other hand, the opening of lower solenoid valve, in the presence of an emergency braking request, the second signal being representative of the pressure value needed for the emergency braking, and in the absence of such a request, the second signal being obtained from a service braking input.
