2 PIPE LEVER

HANDLING OF MANUAL LEVER

1. 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.

2. 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.

3. 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.

GEAR DIMENSIONS

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

1. HANDLING
   Proper care in handling the valve should be taken to prevent damage. Do not drop or throw it.

2. STORAGE
   Store the valve in the protected area from dust, moisture, and direct sunlight. If possible, should be kept in the original packaging.

3. CHECKING
   • Check the product code before installation.
   • Confirm that there is no screw loose or part deformation.

INSTALLATION

1. PRECAUTIONS
   Before installing, clean pipe and valve ends.
   Make sure they are free of dirt, dust and etc.

2. 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.

3. ENVIRONMENT
   If there is a possibility that the fluid and drive part freeze, please take measures to prevent freezing.

4. POSITIONING
   Should be positioned through 90° upward from horizontal. Provide space around the product to allow manual operation, inspection and replacement work.

5. 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.

Recommended torques [N• m]

Valve size [mm]| Torque
T3| L3
25| 025| 3.5
40| 040 to 050| 7
050 to 065| 065 to 080| 10
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

valve. Replace the packing.
Leakage from
valve gland (T3 / L3)| Gland packing is worn or distorted.| Tighten the gland nut.
Replace the gland packing.
