Electromagnetic actuated 5/2 way valve
Home position
Switched position
Faulty switching
The working connec-
tion 2 (A) is vented
via connection 3 (R).
Pressure connection 1
(P) is closed. Connecti-
on 4 (B) is connected to
the pressure connection
1 (P).
The solenoids in the sa-
fety valve are actuated
simultaneously.
Working connection 2
(A) is connected to the
pressure connection 1
(P).
Connection 4 (B) is
vented via the vent
connection 5 (S).
The valve systems
monitor themselves
for correct operation
with every switching
procedure (dynamic
monitoring).
The solenoids are
actuated with a time
difference > 0.5 s.
The dynamic monito-
ring system detects
the delayed actuation
and prevents pressure
build-up at the working
connection 2 (A).
Connection 4 (B) is still
connected to the pres-
sure connection 1 (P) to
hold up any load that
has been raised.
