1. A hydropneumatic valve comprising a hydraulic module (MH) and a pneumatic module (MP), the pneumatic module comprising:
a low-pressure first pneumatic chamber (CP1), comprising a first pneumatic piston (PP1), and a high-pressure second pneumatic chamber (CP2), the two pneumatic chambers being separated from each other by a membrane (M),
a pushing element (EP) adapted to act on the membrane (M) so as to let the high-pressure compressed air pass from the second pneumatic chamber (CP2) to the first pneumatic chamber (CP1),
wherein the hydropneumatic valve further includes a mechatronic module (MM), comprising an electronic management module (MG), and an electromechanical module (ME), said electromechanical module comprising an electric motor (E) and an activation element (E1), and the pushing element (EP) is independently activatable by the hydraulic module (MH) and the electromechanical module (ME).
