Actuator unit; 20-22 bar +5v/-5v power supply; consists of six actuators, one end wall and one connection wall; the connection wall may in some cases be replaced by a pressure reducer; these units are made up into a block by two drawbars; the actuators are electro-hydraulic and work with mechanically reset position control; the actuators must not be unscrewed and are therefore lead-sealed; it follows that a faulty actuator must be replaced as a complete unit
