Abstract:
A valve for regulating the pressure of a gas flow in a duct according to two pressure levels includes a gate whose position is controlled by an actuator with two chambers and 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. The valve further includes 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 chambers of the actuator.
