<p>The device has 2 main valves in series and 2 servovalves operated by an actuator to regulate opening of main valves operated by membranes bounding two gas chambers. The regulator gas inlet and outlet are connected to the first and second main valves' gas chambers respectively. A connection between the first main valve's first and second gas chambers and the second main valve's second gas chamber is made and broken by the first servovalve. The device has two main valves arranged in series and two servovalves (9,29) operated by an actuator to regulate opening of the main valves, which are operated by membranes (3,23) bounding first and second gas chambers (4,5;24,25). The regulator's gas inlet (14) and outlet (15) are connected to the first and second main valves' gas chambers respectively. A connection between the first main valve's first and second gas chambers and the second main valve's second gas chamber can be made and broken by the first servovalve (9).</p> |
