Definitions

  • the invention relates to a device for the torque-free actuation of a closing member for a globe valve, in particular for one in which a bellows designed as a bellows or corrugated tube bridges a passage of a valve rod through the valve housing in such a way that it encloses the valve rod and on the one hand on a closure part of the closing member and, on the other hand, is directly or indirectly attached to the valve housing with an actuator which is detachably connected to the valve rod, in particular an actuator which, when acted upon by a pressure medium, carries out a lifting movement against the action of at least one return spring.

  • at least one helical spring is usually arranged, the respective ends of which execute a relative movement in the circumferential direction to one another during compression and stretching. This relative movement is transmitted to an associated piston which is under spring preload and which in turn is in engagement with the associated valve rod, so that the rotary movement is transmitted from the piston to the valve rod.
  • An actuator which is very simple in construction, in which a piston rod, which is connected in a rotationally fixed manner to its piston, is detachably connected to the valve rod which is led out of the valve housing, is preferably used, for example, in aseptic valves, the typical representative of which, for example, in
