The structure of 103-1 series Hydraulic SCU is more compact and its connection dimension conforms to the internationaI standard, while it is different from 101 and 102 series which are suitable for assembly in the narrow space. It's widely used in the low-speed vehicles, steering control system, such as forklift, tractor, combined harvester, engineering or road construction machinery,and the marine rudder, etc. It can obtain more powerful output steering force through the input force and it operates easily,flexibly and reliably．
