Abstract

Hydraulic control arrangement (1) comprises an emergency operating valve (8) actuated by hand arranged in a control oil flow path. A directional control valve can be adjusted by the emergency operating valve to a position to actuate the consumer when the pilot valve arrangement (47) is in the base position. An independent claim is also included for a rotary disk valve for the above hydraulic control arrangement. Preferred Features: The emergency control valve shuts off the connection to a pressure reducing valve (30) in its switched positions (a, b). The emergency control valve is a rotary disk valve. The pilot valve arrangement has a pressure limiting valve (32) for limiting the pressure in the control oil flow path.
