101(S)-5T & 101(S)-7T Series Hydraulic Steering Control Units
Load-sensing hydraulic steering control units designed for pipe-mounted priority valve systems. The 5T version uses a static load-sensing signal, while the 7T version uses a dynamic load-sensing signal.
Description:
The 101(S)-5T and 101(S)-7T series are load-sensing hydraulic steering control units developed for pipe-mounted priority valve systems.
The 5T version uses a static load-sensing signal and is designed for use with YXL static-signal load-sensing priority valves. The 7T version uses a dynamic load-sensing signal and is designed for use with DYXL dynamic-signal load-sensing priority valves.
The product range includes 101 versions without integrated valves and 101S versions with integrated valve configurations. Available displacements range from 50 to 1000 mL/rev, supporting agricultural machinery, construction equipment and other mobile hydraulic steering systems.
