<p>A pneumatically operated gas-pressure controller is provided having a setting device and a controller, wherein the controlling gas for the energy supply of the controller is drawn on the input side of the gas-pressure controller, fed to the controller by means of a throttle valve and discharged on the outlet side by means of a drain conduit. The controller supplies the setting pressure for the setting device by means of a setting pressure conduit and includes a twin diaphragm system having two diaphragms with different surface areas, the diaphragms are interconnected and arranged one above the other so as to oppose one another. A booster valve is associated with the diaphragm having the smaller surface area and is acted upon by the setting pressure.</p> |
