Abstract
A control circuit throttling valve provided as a controlled dimension receiver in a hydraulic circuit for the control of a final control element, particularly for the control of a lifting unit of a tractor. The valve performs a receiver function under control of a mechanical coupling coupled to a moving part of the final control element which changes the valve throttling section and is adjustable and includes a casing having a control connection and a discharge connection and a movable throttling body provided in the casing in relation to the control connection and the discharge connection such that upon linear or rotational movement of the body it is possible to independently derive an adjusting function and a receiving function.
