Product features
The LCX-6 valve series is based on the existing LX-6 valve
series with the consistent focus on Closed center hydraulic
systems with variable displacement pumps and Compact
design in matter of space / weight reduction.
l Flow-optimized valve design
l High mechanical and electrical resolution
l Compact size and low weight
l Modular design up to 10 working sections
l Types of operation (with/without hand lever):
- Manual
- Hydraulic
- Electrohydraulic (on/off, proportional)
l Application-specic main spools with adjustable
stroke limiter
l Shock/anti-cavitation valves for protection
of actuators

!
The individual single sections of the LX-6 valve series are
used 1:1 in the LCX-6 valve series and are therefore inter-
changeable. The inlet and end modules cannot be combined
or exchanged between the two valve series.
The existing LX-6 product range continues to offer the necessary
and increased exibility for extended functional scopes (e. g.
3-way ow controller for hydraulic systems with xed displace-
ment pumps) – HYDAC product specication EN 5.282.
The LCX-6 is a pre compensated proportional directional
control valve according to the load-sensing principle.
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 the 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.
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 report the highest load pressure for the valve stack
to the inlet section or variable displacement pump.

Modular structure
If only one hydraulic function is needed, the LCX-601 is the right choice.
It consists of one mono section which does not require separate inlet and end plates – everything is included.
It can be customised to different applications and machines.

Modular structure
If two or more hydraulic functions are needed, the LCX-6 valve series provides a modular structure.
It consists of an inlet and outlet section with integrated working function and can be combined
with further single sections from the LX-6 valve series (LCX-602 up to LCX-610).

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

The pressure compensator R must always be

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.
