General operating instructions (continued)
- If the actuator is used in an environment below 5°C temperature, its operating fluid must
be free from the water and moisture contained in it because of possible problems due to
the freeze.
- When you use the valve in a low-temperature environment, put a cover or such that covers
the entire actuator to prevent it from freezing, and check the operating conditions on a
regular basis. (If it freezes, it does not operate normally.)
- Use dehumidified and dust-removed clean operation air. When using highly dry air at a
dew point of -40°C or less, please consult us separately.
- When removing the actuator, be sure to use the "Base plate removing jig". (Failure to so
may cause, damage the Base plate.)
- Regarding the ball valve type, we recommend that you use fully open or fully closed. This
is because the edge of the ball opening remains on the seat (PTFE) when used at an
intermediate opening, so that the sealing performance temporarily deteriorates at the time
of full closing.
