The M+S Hydraulic Hydrostatic Steering units are used in low-speed vehicles which driving
speed does not exceed 60 km/h - such as: building machines, fork-lift trucks, harvesting
machines, off-highway equipment and others. These hydraulic units amplify the torque to the
steering wheels, with no need of hard mechanical connection.
3
HYDROSTATIC STEERING UNITS TYPE XY.../1
The XY hydrostatic steering unit
incorporates an axially displaced
tracing valve and a metering pump in
one housing. The working liquid is
supplied by a separate pump and then
is directed by the metering pump to the
steering cylinders.The XY steering unit is manufactured
with a built-in check valves, and there
is an option for a built-in relief valve in
the inlet.

The HKU.../7 is a hydrostatic steering unit, designed for
integration into systems with built-in hydroaccumulator, achieving minimal energy losses.
"Closed Center - Non Load Reaction"
For the and
steering units is possible to observe Thermal
Shock - condition caused when the hydraulic system
has operated for some time without turning the
steering wheel, causing the

the system to heat up while the steering unit is relatively cool (i.e. there is
more than 500F [100C] difference in the temperature). If, under the condition of
Thermal Shock, the steering wheel is turned very quickly, it is possible to
experience temporary seizure and have the internal parts of the steering unit
damaged. The temporary seizure may be followed by a total free wheeling.

HYDROSTATIC STEERING UNITS TYPE HKUS.../3, 4, 8
The HKUS Hydrostatic Steering unit is based on the HKU unit but has built-in relief and check
valves. Thus M+S Hydraulic achieves one very compact steering unit which reduces the need for
additional hydraulic components in the system.

HYDROSTATIC STEERING UNIT TYPE HKU.../4PB
The hydrostatic steering unit is available for steering medium and large sized
transport vehicles as building and agricultural machines.HKU…/4PB works as standard steering unit with auxiliary port desi ned for flow
providing additional vehicles functions. When the steering wheel is not turned, the flow
will be delivered to port PB. After steering wheel has been turned a part of flow
will be deviated to the steering unit and the flow t rough port PB will be inconstant.It is not recommended to use this unit in systems with auxiliary functions during the

HKUQ200/.../4
HKUQ.../4 is a new series of hydrostatic steering units with an additionally increased flow. The
hydrostatic steering unit type HKUQ…/4 is available for steering medium and large sized vehicles,
allowing easy control either in servo-amplified mode or in emergency operation.HKUQ…/4 is an “Open Center-Non Load Reaction” hydrostatic steering in which restrictor for
amplifying factor from 1,3 to 2,5 is built-in.In accordance with the size of the gear wheel set and amplifying factor, HKUQ…4 has the
following working volume:- from 80 cm3 to 200 cm3 for emergency operation mode (manual steering without servo-
amplifying;- from 100 cm3 to 500 cm3 for normal operation mode (with total flow amplifying).There is no servo-amplifying of flow if low steering speed up to 10 RPM is applied. In steering
speed increase over 20 RPM there is total servo-amplifying of flow. In this mode gear wheel set
flow and restrictor flow are added.

SPECIFICATION DATA
The HKUSD…/4 is a new design of steering unit withtwo gerotor sets. They are mechanically connected.A switch valve, built between the two gerotor sets,switches between two displacements, one displacementfor manual steering and the total of both displacementsfor powered operations. The switch valve is springreturned to the smaller manual displacement wheninlet pressure falls below 4 bar. Above 4 bar the switchvalve connects both gerotor sets to provide full powereddisplacement.This function permits a higher pressure in the steeringcylinder to be achieved and the vehicle steering atoperation to be easier. gfcnwgtawygtawgliwfiwrygierygerig

The HKU(S).../5(D)(T)(TU) range expands the steering units family of M+S Hydraulic with
the (static and dynamic
hydraulic connection to the priority valve)
This range is manufactured in two versions; for modularly and pipe mounting and therefore
were developed the two versions of priority (tracing) valves: PRD... and PRT...
HKU.../5 is designed to be connected to priority valves with built-in relief valves for rated flow
up to [ ] PR .../160.
"Closed Center - Non Reaction and Load Sensing Outlet" version
.
160 lpm 42 GPM - T
The control hydraulic circuits of the HKU(S).../5(T) steering units were designed to ensures
minimal energy consumption (energy losses) in various hydraulic systems, such as those of:
fork-lift trucks, agricultural and construction machines and others.
HKU.../5TU is a steering unit at which the ports R and L in neutral position are connected to the drain line T. This scheme
contributes for the fast discharge of the residual pressure in lines Land R, that usually is “locked” when the steering wheel is
jerky released at neutral position. These steering units do not drive directly the steering cylinders, but they are connected to
hydraulic systems in which they drive the flow amplifiers or other devices.
HKUS…/5D(DT)... is a new generation steering unit, where the dynamic flow to LS-line allows easy and smooth control
when starting the steering. Main features are: Low torque of the steering wheel 0,5÷2,0 Nm [4.5÷18 lb-in] at normal
operating conditions; High steering speed, limited only by the operating flow and the pressure of the supplying pump.

M+S Hydraulic produces steering units type HKUS.../5E(5TE) which have additional EL-port. An electro-hydraulic relaycan be mounted on this port, providing control of the hydraulic system.The relay can be pre-set to normally - open (N.O) ornormally - closed (N.C) contacts, with control range from 0,1 to 50 bars.

HYDROSTATIC STEERING UNITS TYPE HKUS.../5RDT
HKUS…/5RDT is a new generation steering unit with load
sensing dynamic signal and integrated valve functions.
The hydraulic steering unit is applied on all types of agriculture
and construction transportation vehicles which maximum speed
does not exceed 60 km/h.
This sreering unit has low torque and low noise.
HKUS…/5RDT works in a system with a dynamic priority valve
and it is appropriate for machines with increased energy saving
requirements.
The dynamic flow to LS-line allows easy and smooth control
when starting steering.

HKUL is a load steering unit specially developed for large
displacement in order to minimize flow loss. HKUL is
extremely suitable for large vehicles, which maximum speed
does not exceed 60 km/h and works together with dynamic
priority valve.HKUL is available in versions with different valves that are
required in hydraulic steering circuit for protection of the
steering unit and steering cylinders.

The M+S Hydraulic BKH valves are developed to protect thecomponents of the hydraulic circuit: pumps, steering units andcylinders - from overloads, impacts and cavitation. Some of theiradvantages are: easy integration into any hydraulic circuit, easymounting to the steering unit, and quick and easy hose connections.Depending on the design and the built in valves the BKH valves canbe divided into 6 types: BKH1 ... BKH5 and BKHR, with BKH5designed for XY steering units only. The maximum flow rate is incompliance with the whole range of HKU and XY steering units but nomore than 80 l/min. The pressure settings for the entry relief valvesand the shock valves are presented in the table.

PRIORITY VALVES FOR HKUS.../5... TYPE PR...The Priority Valves distribute and trace the hydraulic flow from the supply pump of the
hydraulic system to the hydraulic components which control and run the vehicle.The Priority Valves are used only with the HKUS.../5 (T) hydrostatic steering units.
When connected, the steering unit and the priority valve represent sophisticated hydraulictracing system that controls the flow in both main pipelines of the hydraulic system (theworking and control one) at any time of its operation.
As a static signal, the "LS" signal must be used in systems with circuit stability. Theconnection between the PRT, PRTA priority valves and the HKUS.../5T steering units hasto be as short as possible, but should not exceed [ ] (for iron pipe with[ ] internal diameter). When a rubber hose is used this length ha be evenhorter.

Priority valves with dynamic signal work in a system with dynamic hydrostatic steeringunits type HKUS.../5D (5DT).
