It comprises a body provided with an inlet and an outlet; a moving gate which separates said inlet and said outlet; a seat formed on said body and adapted for said gate to rest against it; hinge means of the gate to the body of the valve; and means for keeping the gate in position against the seat, the latter comprising a body attached to one end of the gate, the gate and said body being hinged to the valve body in such a way that both can rotate around a single hinge pin, which is arranged eccentrically with respect to said body attached to the gate, so that the gate is kept in equilibrium when the pressure inside the valve exceeds 0.1 bar. The pin is aligned with the point of contact between the gate and the seat of the valve body and is detachable.
