The valve has a first control part with a first set point pressure positioning a gate (104) in a first regulated position by comparing downstream pressure (P0) of the gate and the first set point pressure. A second control part with a second set point pressure is provided to position the gate in a second regulated position by comparing the downstream pressure of the gate and a second set point pressure. A permutation part (142) makes one of the control parts to communicate alternately with one of chambers (112, 114) of an actuator. Independent claims are also included for the following: (1) a pressure regulation and stop valve (2) a device for de-icing an air inlet of an aircraft engine nacelle. |
