Lubrication (Continued)
Plug Journals
Plug journal lubrication is dependent upon the materials used in construction of the valve.
• CAST IRON VALVES: Lubricate the journals on the plug using one of these lubricants.
- Lubriplate Clearplex-2 (recommended)
- Amoco FG (alternate)
- Mobilgrease FM 101 (alternate)
- Petro-Canada Purity FG 2 (alternate)
- Phillips Philube PF (alternate)
Note: Ensure lubricant is compatible with flow media.
Thrust Washers and O-rings
Apply a light coat to all surfaces of thrust washers and O-rings using one of these lubricants.
- Lubriplate Clearplex-2 (recommended)
- Phillips Philube PF (alternate)
- Mobilgrease FM 101 (alternate)
- Amoco FG (alternate)
Note:
Ensure lubricant is compatible with flow media.
Packing Adjustment
The stem seal tightening procedure is dependent upon the type of actuator on the valve. If a packing
leak should occur, tighten the packing as follows:
3” – 8" Lever and Nut Operated Valves
Table A: Actuating Torque
Valve Size
Actuating Torque
Standard Packing
in mm ft lbs Nm
3 & 4 100 28 37
5 & 6 125-150 60 81
8 200 104 141
All Other Actuators
Tighten the gland nuts evenly only until the leak stops.
Note:
Do not continue tightening after leak stops. If packing leak cannot be stopped by tightening the
gland nuts, the packing must be replaced.
