guidelines and regulations (e.g. DIN, VDE). If
devices are improperly connected, substantial
material and personal damage may be the
consequence.
2.6 Danger caused by system
pressure
The lubrication systems, which include these
components can be subject to hydraulic
pressure. Therefore, they must be
depressurised prior to performing extension
work, changes, repairs etc.
2.7 Permitted lubricants
You can request a current list of SKF-approved
lubricants through your field employee or the
manufacturing sites.
Please also observe the
authorised lubricant lists issued
by the machine or vehicle
manufacturer.
2.8 Endangering the environment
with lubricants
In their composition, the lubricants approved by
SKF conform to the applicable safety
regulations. However, lubricants are generally
groundwater hazardous susbstances, whose
storage, processing and transport are subject to
special safety measures. Regarding these
hazards, please refer to the material safety data
sheets issued by the respective manufacturer.

environment and at temperatures between -40
°C to +80 °C.
2.10 Disclaimer
SKF will not accept liability for damages caused
by lack of lubricant
by contaminated or unsuitable lubricants
by the installation of non-original SKF
components or SKF spare parts
by unintended use
by faulty installation procedures
by improper electrical connections
by faulty programming of the lubrication
system

3 Design and Function
3.1 Function
The 5/4 way valve DCV5-4+924 is intended for
use in progressive distribution lubrication
systems in the vehicle as well as in the industrial
field. It has one input that can be switched to
use one of four possible outputs. This valve can
be used - especially in combination with the
pump unit KFGS...-...B - to supply, address and
monitor up to four independent lubrication
circuits with lubricant (Figure 1). This 5/4 way
valve DCV5-4+924 can therefore replace up to
four 2/2 way valves.
When switching, there may be a short-term
connection (approx. 0.1 s) between the main
line and non-addressed lubrication lines.
The 5/4 way valve DCV5-4+924 is electrically
supplied with 24 VDC.

3.2 Design
Figure 2 shows the setup of the 5/4 way valve
DCV5-4+924. It is equipped with a hydraulic
input (P) to connect it to the pump as well as
four hydraulic outputs
(1, 2, 3 ,4), which are used to connect
lubrication lines of the different lubrication
circuits.
The electrical connection is made via a 5-pin
plug (M12x1).

4 Installation
4.1 Setup
The valve should be installed in a location that is
protected from dirt, spray water and vibration,
but should be readily accessible to ensure all
further installation tasks can be performed
easily.
The valve is installed upright, as shown in
Figure 2. The assembly dimensions can also be
found in Figure 2.
The valve is fastened to the vehicle or machine
with two screws M8 (torque 16 Nm).
Possible installation borings can be drilled as
seen in Figure 2.
Please observe the following
while drilling and installing:
do not damage existing supply
lines,
do not damage other units,
do not install the valve in the
action range of moving parts,
do not install the valve too
close to heat sources (exhaust,
etc.).
4.2 Connecting the lubrication lines
You can use the connection fittings listed in
Table 1 to connect the lubrication lines to the
inputs and outputs.
Outputs that are not needed must be plugged
with a lockscrew (DIN 910 - M12x1,5 - 5.8).

diameter 6 mm
4.3 Electrical Connection
The 5/4 way valve DCV5-4+924 is electrically
supplied with 24 VDC.
Only one X1 Pin (1, 2, 3 or 4) may
switched at a time.
In combination with the pump unit KFGS...-...B...
, this is warranted by the control module of the
pump unit. In other cases, the control must be
programmed accordingly to ensure this.
The PIN number reflects the number markings
of the hydraulic outputs.
