Product Description:
Hydraulic Steering Unit is used in load sensing steering system. 101S-5, 101S-5L, and 101S-5E series full hydraulic steering gears are all in plate connection mode, and are used after plate connection with PVF* type priority valve.

The 101S-5L series full hydraulic steering gear leads out the pressure signal of the LS port at the LL port and transmits
the signal to the electrical control system; the 101S-5E series full hydraulic steering gear leads out the pressure signal of the A or B oil port at the EL port , to transmit the signal to the electrical control system. 101S-5T, 101S-5TE series full hydraulic steering gears are pipe-connected and used with PVL* or DYXL, YXL priority valves. 101S-5TE series full hydraulic steering gear leads out the pressure signal of A or B oil port at the EL interface, and transmits the signal to the electrical control system.

101-5T series full-hydraulic steering gear is pipe-connected, and must be used with DYXL and YXL priority valves after pipe
connection, and the system safety valve is set on the priority valve. When the 101-5TX series full hydraulic steering gear is in the neutral position, the left and right chambers are connected to the oil return. This kind of steering gear is used together with LFA and LFB flow amplifying valves.
