HANDLING OF MANUAL LEVER
Attention
• The lever handle is removed and shipped.
• The lever mounting direction can be changed in units
of 45 degrees.
• Do not apply excessive torque to the lever.
• Do not strike or extend the lever with a tool.
• The arrow on the plate indicates the direction of flow.
LEVER HANDLE INSTALLATION (Casting lever)
• Plate of position indicator is attached on the valve by
C-type snap ring. Install the manual lever on it
tightening the bolt.
• The position of manual lever can be changed
according to piping circumstances.
LEVER HANDLE INSTALLATION (Pipe lever)
• Remove the bolt and nut from the lever.
• Loosen the knob bolt. Insert the lever into the
connector.
• Tighten the bolts so that the lever does not fall off.
• Fix the lever with the knob bolt.

INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS
HANDLING & STORAGE
HANDLING
Do not drop or throw the product as it may break.
STORAGE
Store away from dust, moisture and direct sunlight.
If possible, store in the original package.
CHECKING
• Check the product code before installation.
• Make sure that the bolts are not loose.
INSTALLATION
PRECAUTIONS
• Flush the pipeline carefully before installing the
valve. Foreign particles, such as sand or pieces of
welding electrode, will damage the ball and seats.
• For valves with specified flow direction (VR) or with
ST / SC option, check the arrows on the product
before piping.
• When the flow path is subjected to a high pressure
from arrow, it may leak slightly to the low pressure
port. (TR / LR)
PIPING FLANGES
• Gasket should be selected appropriately to suit the
fluid, pressure and temperature.
Use spring washer to prevent from decreasing
surface pressure gasket when the temperature
change happens frequently.
• Tighten all bolts using crossover method to load the
joint evenly.
• Wafer type ball valve is put between two seats of
flanged-end and tightened with long bolts. (BS)
ENVIRONMENT
If there is a possibility that the fluid and drive part
freeze, please take measures to prevent freezing.
POSITIONING
Should be positioned through 90° upward from
horizontal. Provide space around the product to
allow manual operation, inspection and replacement
work.
CAUTIONS FOR MAINTENANCE (T3 / L3)
Do not keep warm for maintenance of the valve
gland.
TIGHTEN THE GLAND NUTS (T3 / L3)
• Check that there is no leakage from the gland
packing.
• If it leakage, tighten gland nuts by alternately.
Do not over-tighten the gland nuts.

year.
Inspection items
• Confirm operation of opening and closing.
• Confirm whether screws are loose or not.
• Confirm the fluid temperature or pressure.
• Confirm the leak from valve stem.
• Confirm the bolt tightening torque.
