More Information
Summary:A latch device (12) for a hydraulic valve (10) is proposed. The latch device (12) comprises a housing (22) and a latch shaft (26), which is supported such that it can move in the housing (22). In order to create a latch device (12), independent of the hydraulic provisioning, the provision of at least one magnetizable ring beam arrangement (38), which is supported on the latch shaft (26), and an electric solenoid arrangement (40), located on the housing (22) around the ring beam arrangement (38) is also proposed, wherein by the supply of current to the solenoid arrangement (40), a positioning force can be produced on the ring beam arrangement (38). Furthermore, a hydraulic valve (10) with the corresponding latch device (12) and a hydraulic arrangement (92) for such a valve (10) are also proposed.
