This valve (100) comprises: a body (101); a first channel (111) for channelling the flow of a fluid; a second channel (112) for channelling the flow of a fluid; a first valving element (130) which is movable translationally in a first direction (X112), between an open position and closed position of the or each first channel (111), the body (101) forming a first seat (123) for the first valving element (130); and a second valving element (130) which is movable translationally in a second direction (X112), between an open position and a closed position of the or each second channel (112); the first direction (X112) and the second direction (X112) being parallel or coinciding with each other. The first valving element (130) defines a housing (140) for the second valving element (130). The first valving element (130) forms a second seat (136) for the second valving element (130).
