Valve device for use as cartridge valve or screw-in cartridge valve in hydraulic systems, has valve housing and valve piston connected with operating magnet device through coupling device, where coupling device has coupling elements

摘要

The valve device has a valve housing (3) and a valve piston (5), which is connected with an operating magnet device (1) through a coupling device (15). The coupling device has coupling elements, which are brought in coupling engagement with each other. The coupling elements are locked with each other such that a form-fit coupling engagement is formed. The coupling element of the operating magnet device has a locking projection (57), which is locked with a counter detent (59) provided as a coupling element of the valve piston.
