Abstract: The rapid closure device for the pressurization of vessels used primarily for isostatic pressing of sintered powders comprises a removable jack-operated spherical plug valve fitted within a cylindrical shell between a double-acting piston slidably mounted in an adjustable seal plug and a valve-seat lining placed in the trued base of the shell. The plug valve is rotated and maintained in the closed position by means of a fluid under pressure which is also directed towards an adjustable pressure multiplier comprising a two-stage ram slidably mounted within a low-pressure cylinder and a highpressure cylinder.
