• Refer to back page 8 for
changing the type of
actuation.
Note) Impact resistance: No malfunction occurred when tested in both the axial and right angle directions
of main valve and armature (tested in both energized and de-energized states).
(Values at the initial period).
Vibration resistance: No malfunction occurred when tested in a one-sweep test between 45 and 2000
Hz, in both the axial and right angle directions of main valve and armature (tested
in both energized and de-energized states). (Values at the initial period).
