A direct stopcock for liquids, of the type in which the sealing is achieved by a valve that has two opposite faces flat forming an angle of reduced opening between them and susceptible to apply the valve, on both sides, against asbestos existing in the body of the key, which is essentially characterized in that the body of the key is constituted by the meeting or grouped of four parts: an input conduit; an exit route; a sleeve in which the inlet and outlet pipes fit, provided with a lateral opening; and an internally threaded tube that fits on the sleeve, perpendicular to its axis, in which tube is fixed the hub or piece that serves as a guide for the rod or asparagus for actuating the valve.
