Specifications
Note) Impact resistance: No malfunction from test using drop impact tester, to axis and right angle directions
of main valve, each one time when pilot signal ON and OFF. (Value in the initial
stage)
Vibration resistance
: No malfunction from test with 45 to 1000 Hz one sweep, to axis and right angle
direction of main valve, each one time when pilot signal ON and OFF. (Value in the
initial stage)
1. Lubrication
Since this valve needs lubrication, use
turbine oil Class 1 (ISO VG32).
2. Refer to pages 1309 and 1316 for infor-
mation about the pressure applied to
piping and ports, quality of air and pip-
ing for vacuum applications.
