Abstract

Valve member (3) has a limited freedom of rotation and/or translation in a plane perpendicular to the system axes and around spindle system (5). A pretensioned spring (4) is arranged inbetween valve member (3) and the spindle eccenter (5). A complete closing stroke of spindle (5') forces the valve member consecutively to: rotate, translate onto the seat and to be pressurized according to the angle-formula in the table (VM = valve member). Within practical limits, all 4 angles can be given any value guiding pins (6), running through slots in the sidewalls of housing (1), stop the rotation of valve member (3) when its sealing face is aligned with the central seat axis and then maintain the translatory movement of the spherical sealing face onto the seat. Continuation of the spindle rotation pressurizes the valve member to its preset value. Opening the valve demands the reverse procedure.
