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.
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.

| Valve size [mm] | Torque | |
| T3 | L3 | |
| 25 | 025 | 3.5 |
| 40 | 040 to 050 | 7 |

| 080 to 100 | 100 to 125 | 14 |
| 125 to 150 | 150 | 20 |
MAINTENANCE
Do the routine maintenance at least once in half a 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.
TROUBLESHOOTING
| Problem | Cause | Solution |
| Stop in the mid position. | • Biting of valve seat. • The scale has adhered to the valve ball. | Remove a foreign object. |
| Leakage from valve body | • Valve cap get loose. • Valve body is damaged. | Replace the valve. |
| Leakage from valve seat | Seat is worn or damaged. | Replace the valve. Replace the seat. |
| Leakage from valve stem | Stem packing is worn or distorted. | Replace the valve. Replace the packing. |
| Leakage from valve gland (T3 / L3) | Gland packing is worn or distorted. | Tighten the gland nut. |
| Replace the gland packing. |
