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.

HANDLING OF GEAR
• The handle wheel of the gear is removed and
shipped.
• Insert the handle into the gear shaft.
• Insert a pin into the hole in the handle.
HANDLING & STORAGE
HANDLING
Proper care in handling the valve should be taken to
prevent damage. Do not drop or throw it.
STORAGE
Store the valve in the protected area from dust,
moisture, and direct sunlight. If possible, should be
kept in the original packaging.
CHECKING
• Check the product code before installation.
• Confirm that there is no screw loose or part
deformation.
INSTALLATION
PRECAUTIONS
Before installing, clean pipe and valve ends.
Make sure they are free of dirt, dust and etc.
PIPING FLANGES
• VR type has a flow direction. Install the valve
accordingly.
• Specify the ST option if a steam fluid. Flow direction is
restricted by ST option. (BR / BS)
• 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)
• In the TR / LR type, when the flow path is subjected to
a high pressure from arrow, it may leak slightly to the
low pressure port.
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.
