Improved steam valve of the piston type and exchangeable and external annular seal, essentially characterized in that the sealing member, longitudinally sliding inside the main body, laterally has a rack toothing in conjugation with the cylindrical toothing formed by a cogged pinion of a cylindrical element disposed perpendicularly and crossing with respect to the ideal axis of the valve and of the obturator, said cylindrical element being housed in a lateral expansion and with a perpendicular axis, a cup-shaped expansion, derived laterally from the main body of the valve, also figuring in said housing, for guiding the cylindrical element and for closing the assembly thereof with respect to the main body, an annular seal that is maintained in position and permanently tightened by an upper bushing, forming a flange that is arranged parallel to the plate located in the embouchure of the cup-shaped housing.
