BZZ hydraulic steering unit for komatsu forklift power load sensing steering valve assembly black color iron cast

BZZ series hydraulic steering unit is consisted of one pair of rotary valve and one pair of
gerotor. Via the steering column, the steering unit links the steering wheel, when the steering
wheel rotates, the oil flows out of the supply pump of the steering system , through the rotary
valve and the gerotor , to the cylinder’s port left or right ( depend upon the rotation direction).
The gerotor supplies the oil to the steering cylinder in proportion to the angular rotation of the
steering wheel. If the oil flow out of the supply pump of the steering system is too small, the
steering unit can work as the manual pump.

As for load sensing steering system, the steering system and the
operational system may use the same pump through the priority
valve or the load sensing system can distribute the surplus oil of
the steering system into the operational system. Meanwhile, if the
pump with load sensing is used , the load sensing will have obviously
productive results.

The LS port of the load sensing steering unit has to connect with
priority valve or LS port of load sensing pump, so that the signal of
the steering load pressure of the steering unit can be transferred to
priority valve or load sensing pump through oil hose ( we suggest that
the length of the hose is ≤2 m), to control the oil volume supplied to
steering unit by the control system.

Hydraulic steering control unit is designed for steering function of self-propelled work machines.

It is widely used on construction machinery, forklift, tractor, harvester, ship rudder and other machines.

The advantages of our hydraulic steering control units are: low cost, highly reliable, easy operate.
