4.5.4.3 Example of CAN bus control with
5/4 directional solenoid valve
The 5/4 directional control valve is intended for
use in progressive feeder lubrication systems
and in the industrial sector. It possesses an in-
put which can be switched to one of the four
outputs at a time. Using this valve, especially in
combination with the KFG CAN bus pump unit,
up to four independent zones can be supplied
with lubricant, controlled and monitored. The
5/4 directional control valve thus replaces up
to four 2/2 directional control valves. During
the switching process, there may be a brief
connection (approx. 0.1 s) between the main
line and non-actuated lubrication lines. The
DCV5-4+924 5/4 directional control valve is
electrically actuated with 24 VDC.
