Регулирующее устройство включено между регулировочными клапанами устройства предварительной регулировки и потребителями рабочей среды и подсоединено к трубопроводу для рабочей жидкости, а также к обратному трубопроводу. Оно состоит из клапанного блока со сквозными продольными отверстиями для связи с многожильным шлангопроводом, ведущим к устройству предварительной регулировки. В клапанном блоке расположены посадочные отверстия для предварительно настроенных трехходовых двухпозиционных клапанов, а также выпускные отверстия для присоединения рабочего цилиндра прямого управления.A control device is connected between the control valves of the preliminary adjustment device and the consumers of the working medium and is connected to the pipeline for the working fluid, as well as to the return pipe. It consists of a valve block with through longitudinal holes for communication with a multi-core hose line leading to a preliminary adjustment device. In the valve block, there are landing openings for pre-configured three-way on / off valves, as well as exhaust openings for connecting the direct control slave cylinder.
