Date May 22, 1998The electrohydraulic control unit comprises at least one +E,fra 3/2+EE directional control valve 2 which is switched by an electromagnet 3 connected to an intrinsically safe power supply. The components of the +E,fra 3/2+EE directional control valve 2 are arranged in a valve cartridge 18 inserted into the valve casing 1 on a common axis and with adjustable clearance with respect to the electromagnet 3. The control plunger 12 of the electromagnet 3 transmits the switching force through a precompressed spring buffer 4 to the stoppers 24, 30 of the +E,fra 3/2+EE directional control valve 2. |
