General information
and functional description
The LX-6 is a proportional directional control valve according
to the load-sensing principle pre compensated.
The nominal ow rate to the working ports A and B is 160 l/min.
The main spool
2.1
determines the ow direction and
magnitude of ow rate.
Pressure control valves
2.4.3
and
2.4.4
are providing shifting
pressure to the left and right side of the main spool
2.1
to
control its position. The level of electric current determines the
level of pilot pressure and therefore the position of the main
spool.
Adjustable stroke limiters
2.4.1
and
2.4.2
can be set mechanically
to limit the maximum ow rate to the working ports A and B.
A
T
T
P
B
l Adjustable load sense pressure limitation (mechanically or
electro proportionally) causes the compensator to block ow
to the working ports A or B independently
l Direct-mounted option blocks for remote control
of LS and pilot oil supply
l End plates with additional pilot oil
supply options
l Areas of application:
- Cranes - Forestry
- Lifting platforms - Municipal vehicles
- Drilling machinery - Truck applications
- Construction - Stationary applications
- Agriculture
The pressure compensator
2.7
keeps the ow rate to the
actuator constant, even if the system pressure varies.
Pressure changes at the pump or working ports A and B
are compensated for each working section individually.
The maximum operating pressure can be adjusted by
LS pressure limitation for working ports A and B separately.
Shock / anti-cavitation valves
2.3.2
protect the working
ports A and B from pressure peaks. Anti-cavitation valves
2.3.1
protect the system from cavitation.
Shuttle valves are integrated into the working sections to
signal the highest load pressure for the valve stack to the inlet
plate or variable displacement pump.

Asymmetrical spools (on inquiry)
The main spool for asymmetrical ow rates can only be dened within one row in the table above.
The higher ow rate must be assigned to working port A (e.g. 160 – 130, 100 – 036, 150 – 090).

Main spool in neutral position
(Type CR – A/B unloaded to T)
Main spool out of neutral position
(P → B, A → T)
P is not connected to the working ports A and B when the main spool
2.1
is in neutral position(Fig. A). The compensator spool
2.5
is moved to left against the compensator spring
2.6
by pump pressure and blocks ow to the main spool.
When the main spool
2.1
is operated out of the neutral position (Fig. B), the load pressure (LS pressure) of the working port A or B
is connected to the spring chamber of the pressure compensator and moves the compensator spool to the right into a corresponding
controlled position.
The ow rate through the main spool (= metering orice) is kept constant by the pressure compensator when sections are in parallel
operation with different load or pump pressures.
The characteristic ow rate curve of a main spool can be adapted and optimized to each application by using the different pressure
compensator spring types Y, B, N or G.
Basic types of pressure compensator / load holding function
R
Pressure compensator spool - released
with load holding function (standard type)
!
The load holding function is not
free of leak oil, the hydraulic
schematic / symbol is simplied
The pressure compensator R must always be
indicated in the type code with the corresponding
compensator spring type Y, B, N or G.
L Load holding function only
!
The load holding function is not
free of leak oil, the hydraulic
schematic / symbol is simplied.
Different load or pump pressures are not
compensated when sections are in parallel operation.
The ow rate to the actuator depends on the pressure
difference between pump pressure and load (LS pressure).
Main spool denition and detailed system setup on inquiry.
The pressure compensator spring
2.6
is not indicated
for the load holding function in the type code.
