A method and an apparatus for controlling the rate of pressure applied to an air controlled device. The apparatus includes a flow restrictor, a regulator, and a dome loaded regulator. The regulator is configured to be operatively connected to a pressure source and is set to a first selected pressure. The flow restrictor is arranged to control the rate of applying pressure to the air controlled device after the first pressure is reached. The dome loaded regulator is in communication with the regulator and the flow restrictor such that the regulator and the flow restrictor alternately determine the flow rate from the pressure source to the air controlled device. The method includes setting a predetermined parameter and automatically reducing the rate of applying pressure to the air controlled device after the predetermined parameter is reached.
