  • the three-way valve is in the closed position shown 9 switched so that the first gas line 7 and second gas line 6 are interconnected. Based on these Circuit is the gas pressure at the inlet 14 and thus in second gas space 5 is present, introduced into the first gas space 4. There is therefore no pressure difference between the first gas space 4 and the second gas space 5. Due to the lack of pressure difference the membrane 3 does not exert any force on the main valve and the valve plate 1 of the main valve is by the spring 10 held in the closed position.
  • the three-way valve 9 is in a Positioned in which it is the first gas line 7 with the third gas line 8 connects. Because of this connection the pressure in the first gas space 4 to the third gas space 11 and thus Relieved to the outlet side of the first main valve. The Pressure in the first gas space 4 is therefore rapidly reduced. by virtue of the resulting pressure difference between the first gas space 4 and the second gas chamber 5, the main valve is opened because of Pressure in the second gas space 5 is higher than the pressure in the first Gas space 4. The valve disc 1 is thus opposed to the membrane 3 the force of the spring 10 moves up and away from the valve seat 2 lifted off, creating the opening cross section of the main valve is released.

It doesn't matter whether the first servo valve 9 or the second servo valve 29 is modulated. A Modulation can also take place if the second servo valve 29 is in the fully open position because the modulation then takes place exclusively via the first servo valve 9.
