Abstract: A valve for controlling a hydropneumatic device for pressure intensifying having a working plunger and an intensifier plunger for pressure intensifying, the intensifier plunger being designed to move the working plunger hydraulically with a comparatively high transmission ratio on account of a pneumatic actuation, the valve having a differential plunger arrangement with a first plunger with a first active plunger face in a first pressure space and a second plunger with a second active plunger face in a second pressure space, the first plunger being coupled to the second plunger, the first pressure space being equipped with a first connector for, for example, a pneumatic return stroke space of the working plunger, and the second pressure space being equipped with a second connector for a pneumatic pressure source which differs from the return stroke space.
