Solenoid voltage and solenoid version
A manifold can merge up to 14 size 2 valve sections.
This number can be increased by combining with a PSL 5 or PSL 3. In this case, transition plates are used and each size has its own
tension rod.
Limits to the maximum possible number of valve sections result from:
a) tension rod strength
b) internal control oil supply for the electro-hydraulic actuation
c) the available control pressure difference for supply to the rear valve sections

2.2 Connection block
Connection blocks come in two basic variants:
■
PSL: Connection block with integrated 3-way controller for use in open centre systems with constant pumps
■
PSV: Connection block without 3-way controller for use in closed centre systems with variable pumps or for simultaneous supply of
two or more manifolds from a shared constant pump
PSL PSV
Depending on the configuration, the connection blocks contain:
a.
A 3-way controller for open centre systems with constant pump
b.
A pressure-limiting valve to ensure maximum system pressure
c.
An LS pressure-limiting valve to cap or relieve LS pressure
d.
A damping element to attenuate LS signal oscillation
e.
A pressure reducing valve for internal control oil supply to the downstream valve sections
f.
Various additional elements (e.g. idle circulation valve, power-beyond function, P-gallery shut-off, mechanical locking of the 3-way controller)

Standard connection block with integrated 3-way controller.
Pressure-limiting valve: direct actuation
PSL 3U…/…-2
PSL UNF 2U…/…-2
Additional idle circulation valve for automatic reduction of circulation pressure.
The idle circulation valve opens when the current LS pressure drops below 25% of pump pressure. Electro-hydraulic
actuation with internal control oil supply requires a pump ow rate of at least 80 lpm, pilot pressure will otherwise
not sufce to shift the spool valve. Load pressure must be at least 20 bar.
Pressure-limiting valve: pilot-controlled
PSL 3 Z…/D…-2 Additional release valve for quick release of pressure in neutral position.
Once all valve sections signal an LS pressure below around 1/3 of the 3-way controller's spring cavity pressure, the
release valve opens to the reux. The LS pressure in the 3-way controller’s spring cavity is released to R.
Common applications include oscillation-sensitive systems and combinations with load-holding valves.
Pressure-limiting valve: direct actuation
NOTE
A SL2-ZPL 22/7 spacer plate is required afterwards
PSL 3 Y…/…-2 Special version with an additional connection suitable for pressure loads for the 3-way controller's outow (power
beyond function).
You can connect a second manifold to the F port. The rst manifold’s valve sections are prioritised. The downstream
manifold receives the excess volume.

P-line cut off to safely shut off pump and consumer from one another and prevent undesired movements.
The P channel incorporates a piston controlled by a 2/2-way directional valve. When unpowered, the piston securely
seals the P channel; actuating the 2/2-way directional valve opens the P channel.

Ordering example: PSV 4 N B 61ZM/220/200-2
– Setting for main pressure-limiting valve: 220 bar
– Setting for LS pressure-limiting valve: 200 bar
NOTE
When using a P-line cut off, there is an additional pressure drop in the P channel that can lead to the
downstream sections no longer reaching nominal ow.
Nominal ow undercut depends on
a) control pressure difference in the variable pump’s pump controller,
b) the position of the valve sections in the manifold and
c) ow rate through the P-line cut off.
Nominal ow undercut can reach up to 30% of Q

R 2-way controller with check valve function.
In the event of a shortage in supply, the controller prevents return ow from the load line
(A or B channel) to the P channel.
Only in conjunction with 2-way controller spring coding 2 and 5.
D 2-way controller with release of pressure
The controller prevents pressure creep in the P channel between the 2-way controller and
valve spool.
Common applications include consumers with very low load pressures and without
additional check valves. With standard 2-way controllers , phantom movements may occur
here. The pressure controller prevents this.
In applications with check valves, the pressure controller prevents undesired check valve
intervention.
B 2-way controller with release of pressure and check valve function
Check valve function:
In the event of a shortage in supply, the controller prevents return ow from the load line
(A or B channel) to the P channel.
Release of pressure:
The controller prevents pressure creep in the P channel between the 2-way controller and
valve spool.
Common applications include consumers with very low load pressures and without
additional check valves. With standard 2-way controllers, phantom movements may occur
here. The pressure controller prevents this.
In applications with check valves, the pressure controller prevents undesired check valve
intervention.
Only in conjunction with 2-way controller spring coding 2 and 5 (see "Table 12").

Pre-selector valve section without 2-way controller.
The pre-selector valve section shuts off the P channel in neutral position. Once the pre-
selector valve activates, it supplies either the downstream valve sections (switching
position b) or a second manifold connected to port A (switching position a).
■
8: LS signal is signalled from port A (switching position a) and the downstream valve
section (switching position b). Standard configuration if an open centre valve is used
on port A.
■
81: LS signal is only signalled by downstream valve section (switching position b).
Is used if a closed centre LS valve is connected to port A; the LS signal is then usually
signalled externally to the variable pump.
Common applications include loading cranes, concrete line pumps and lifting platforms. In
these, the pre-selector valve is used to switch between operating the crane or mast and
the outriggers. The pre-selector valve can further also be used as a P-line cut off in safety
functions.
Only in conjunction with

PSV connection block
■
Circuit symbol L or H (see "Table 14")
■
Actuation coding E… (see "Table 22")
NOTE
When using a pre-selector valve, there is an additional pressure drop in the
P channel that can lead to the downstream sections no longer reaching
nominal ow.
Nominal ow undercut depends on
a) the control pressure difference of the 3-way controller (PSL) or variable pump’s
pump controller (PSV),
b) the position of the valve sections in the manifold and
c) the ow rate through the pre-selector valve or P-line cut off.
Nominal ow undercut can reach up to 30 % of Q

LW, MW, HW, JW, OW Special version with broad tting tolerance.
■
Advantage: Reduces risk of jamming spool valve in
systems prone to soiling
■
Drawback: higher spool valve leak rate
LW MW HW JW OW
LB Special version with minimal release of pressure from A and B channel when spool valve in idle position.
Common applications:
Combined with load-holding valves that require closed spool valve in neutral position in line with safety
requirements. The LB spool valve in such a case prevents trapping pressure between spool valve and load-
holding valve and allows the load-holding valve to close reliably.
LB
G 3/3-way directional spool valve for single-acting cylinders
The G spool valve can be combined with any valve section, port B is sealed with a tapped plug when doing
so.
No LS signal is produced when load drops. If used in conjunction with electro-hydraulic actuation and a PSL
connection block with standard 3-way controller spring (see "Table 4"), this can result in the internally
generated pilot pressure not being sufcient to fully shift the spool valve.
Load reduction is throttled using the spool valve’s outow edge. If desired, the maximum reduction rate can
be capped using a separate ow control valve (e.g. type SB as per D 6920).
To obtain pressure-compensated load reduction, you can alternatively also use an N or NX spool valve.
G
X, W
Special spool valve in conjunction with P d A in neutral position
Common applications:
Fan drives, generator drives or other consumers requiring a specic ow rate when unpowered
for safety reasons.
■
X: 2/2-way directional spool valve
Maximum ow rate in neutral position. By shifting the spool valve to switching position b,
the ow rate can be reduced to zero proportionally.
■
W: 4/2-way directional spool valve
In neutral position, the maximum ow rate is towards A-side. By shifting the spool valve to
switching position b, the direction is reversed and the ow rate is towards B-side. Decelerat-
ing consumer to zero as well as proportional ow rate control are only possible to a limited
degree. This makes the W spool valve suitable primarily for applications with constant speed.
Available versions:

NOTE
The valve spools’ sizes are designed to make actual ow rate slightly higher than Q

in practice.
You can use stroke limitation to limit the maximum ow rate. Setting values are specied in lpm.
Ordering example: SL 2-A2 L 40/40/EA [35/30]
NOTE
When using a pre-selector valve (coding 8 as per "Table 11: Valve section, 2-way controller") or a P-line cut off (coding PSV 4 N
or PSV UNF 4 N as per "Table 3: Connection block basic types"), there is an additional pressure drop in the P channel that can
lead to the downstream sections no longer reaching nominal ow.
Nominal ow undercut depends on
a) the control pressure difference of the 3-way controller (PSL) or variable pump’s pump controller (PSV),
b) the position of the valve sections in the manifold and
c) the ow rate passing through the pre-selector valve or P-line cut off or intermediate plate to P pressure limitation.
Nominal ow undercut can reach up to 30% of Q
nominal
, see "Table 15: Flow rate".
With valve sections without 2-way controllers (coding 1 or 8 for Q
A...
as per "Table 11"), it is possible to calculate the ow rate using
the following formula:
Q
A/B
= ow rate to port A or B
Q
nominal
= nominal ow rate of valve spool at pressure difference of 6 bar
Sp
controller
= control pressure difference of the 3-way controller (PSL) or variable pump’s pump controller (PSV)
Example:
■
PSL connection block, standard 3-way controller spring (9 bar)
■
PSL connection block, 3-way controller with heavy-duty spring (14 bar)
■
PSV connection block, pump controller with 25 bar standby pressure
NOTE
The calculated values are rough reference values! They apply only to the highest-load consumer. If multiple consumers are being
actuated in parallel, the pressure difference may be considerably greater at the lower-load consumers.

For spool valves with 2-digit order coding, the rst number indicates nominal ow rate on the A-side (Q

Differential function.
The differential circuit (regeneration function) makes it possible to reach considerably
greater cylinder extension speeds at the same pump ow rate.
At the same time, however, the force available becomes lower because the pressure applied
on the cylinder’s piston and rod side is identical; only the effective areas differ.
This makes the differential function unsuitable for loads that drag on the cylinder.

Only twin solenoids with manual override (coding -...T or -...TH) are possible.
If a twin solenoid without manual override was chosen for the valve section’s electro-hydraulic actuation, the same twin solenoid type is

NOTE
■
Only twin solenoids with manual override (coding -...T or -...TH) are possible.
■
If a twin solenoid without manual override was chosen for the valve section’s electro-hydraulic actuation, the same twin
solenoid type is automatically used for the LS pressure limitation’s electro-proportional actuation, but with additional manual
override.
■
If the twin solenoid type is not possible with manual override, coding -G...T is used by default.

5.2.3 Converting the connection block from PSL to PSV
The connection block type PSL 3../D...-2 or PSL UNF 2../ D...-2 can be converted at any time to a connection block for control pump
systems (correct type then type PSV 3 S../D...-2 or PSV UNF 3 S../D..-2). To do so, change or swap the parts listed below.
PSL .../D...-2 PSV ...S/D...-2

Screw 7997 019
NOTE
The screws, grub screw or orice are stuck in with
threadlocker uid. During the conversion process, secure
the parts against coming loose again. If type PSV is to
be converted to type PSL, the existing tapped plug must
also be exchanged for dampening screw S (7778 301) (not
applicable for types PSV 3 S./..-2 or PSV UNF 3 S./..-2, as
there is already one there).

5.2.4 Notes on spool valve exchange
The valve spools are not specially adapted to a spool block. This means that spool valves can be exchanged at any time to bring them in
line with any changes in consumer requirements.
In doing so, the following must be observed:
1
End plate side
2
Connection block side
3
Metering ports
Notes on exchanging the valve spool
1 Unscrew screws 1 (ISO 4762-M4x12-8.8-A2-70), take off spring housing
2 Unscrew screw 2 M4x30
3 Take off spring package with spring plates 3
4 Unscrew screws 4 (ISO 4762-M4x35-8.8-A2-70)
5 Pull the lever housing out of the spool block together with the valve spool 5, 6
6 Remove retaining washer DIN 6799-2.3 and bolt 7, 8
7 Proceed in reverse order to reassemble with (new) valve spool
NOTE
When assembled, the valve spool’s metering ports must always face towards the end plate!
Exception: Valve spools with coding 40 do not have metering ports and can be installed any way around.

5.3 Operating instructions
Note product configuration and pressure / ow rate
The statements and technical parameters in this documentation must be strictly observed.
The instructions for the complete technical system must also always be followed.
NOTE
■
Read the documentation carefully before usage.
■
The documentation must be accessible to the operating and maintenance staff at all times.
■
Keep documentation up to date after every addition or update.
CAUTION
Risk of injury on overloading components due to incorrect pressure settings!
Risk of minor injury.
■
Pay attention to the maximum operating pressure of the pump and the valves.
■
Always monitor the pressure gauge when setting and changing the pressure.
Purity and ltering of the hydraulic uid
Fine contamination can significantly impair the function of the hydraulic component. Contamination can cause irreparable damage.
Examples of ne contamination include:
– Metal chips
– Rubber particles from hoses and seals
– Dirt due to assembly and maintenance
– Mechanical debris
– Chemical ageing of the hydraulic uid
