ゃ断弁。(1) A valve caning that has an inlet and an outlet and a main valve opening between them, a main valve that has a hollow piston and opens and closes the main valve opening, and a main valve that constantly closes the through hole of the main valve. In a loading arm shutoff valve having an auxiliary valve pressed by a spring against the main valve, and an opening/closing means for the main valve and the auxiliary valve, the opening/closing means for the main valve and the auxiliary valve include: It has a rod extending slidably through the center of the auxiliary valve, and a rod elevating means that engages one end of the rod, and the auxiliary valve and the rod are connected by an unlockable locking means. A working rod is connected and operatively connected to the diaphragm valve so as to face the free end of the rod opposite the rod lifting means, the working chamber containing the diaphragm valve being connected on the one hand to the flow of the liquid to be supplied. A locking means is provided by means of an actuating rod which communicates with a constriction provided in the channel and, on the other hand, with a conduit opening into a tank supplied with liquid, and which moves towards the rod when the diaphragm valve is actuated. A shutoff valve is characterized in that the valve is shut off by unlocking.
