Functional description
The DUNGS safety solenoid valve is
an automatic shut-o valve operated
with auxiliary power.
The electromagnetic drive opens
against the force of the closing spring 4.
If the auxiliary power is interrupted
(operating voltage), closing spring 4
closes the valve within 1 second.
The closed position of the valve can
be monitored by a mountable closed
position signal contact.
The stroke of armature 5 can be limited
by the setting screw 8.
The hydraulic brake 10 permits slow
opening. Fast stroke 9 can be ad-
justed.
