Abstract (en)

[origin: EP2241764A1] The valve (100) has an inlet connected to a pressure line (P), and an outlet connected to a line with a lower pressure in the pressure line. First and second pressurization surfaces (F1, F2) are provided with different sizes. A channel (130) controls the pressure of the pressure line on a third pressurization surface (F3) opposite to the first pressurization surface. Another channel (140) controls the pressure of the pressure line on the second pressurization surface in opening condition of the seat valve.
