2. USAGE
Our TMi actuators, driven by electric power, can be used to control
the opening and closing of a wide range of valves and dampers.
Basically it is available to multi turn valves such as gate, globe or penstock,
which require valve stem to multi turn in oder to reach both ends, fully opened
and closed position.
However, regardless of the multi-turn actuator, it can operate and control
quarter turn valves such as ball, butterfly or plug with the appropriate
combination with gearboxes.

3. STORAGE
Storing actuators indoors is preferable.
If outdoor storage is unavoidable for a long time, store actuators on the
pallet in a dry place sheltered properly. Also it is recommended, if in a damp
environment, to connect wiring to space heaters to avoid condensation in
switch case.
A dry agent pack is put inside switch unit and take it out before trial
operation.
