Dual Regulation Level Valve And De-Icing Device For An Air Inlet Of An Aircraft Engine Nacelle Incorporating Said Valve

A pressure regulation and stop valve comprising:

• a gate arranged in said pipeline, the position of which gate is controlled by an actuator comprising first and second chambers;
• a first control means with a first set point pressure P1 making it possible to position the gate in a first regulated position by comparing a pressure Pav downstream of the gate and the first set point pressure P1;
• a second control means with a second set point pressure P2 making it possible to position the gate in a second regulated position by comparing the pressure Pav downstream of the gate and the second set point pressure P2;
• and
• permutation means for making the first control means or the second control means communicate alternately with one of the first and second chambers of the actuator, wherein the permutation means comprises:
• first and second outlets;
• and
• wherein the valve comprises means configured to make either the first and second outlets of the permutation means communicate with the first and second chambers of the actuator, or one of the first and second outlets communicate with one of the first and second chambers.
