Operation
- Direction of opening is indicated by an arrow cast on to part of the indicator post body.
- Fully open and close valve before applying pressure, using the wrench supplied as part of the indicator post. Longer wrenches or "cheaters" should not be used as excessive leverage may damage the indicator post or the gate valve to which it is connected.
Maintenance
-
Place three or four drops of lubricating oil about four times a year in hole located on top of operating stem nut and turn operating stem nut to distribute the oil.
-
If for any reason it becomes necessary to replace the operating stem nut, proceed in the following manner:
- Remove eye bolt IP–3 and hex head bolt IP–9 and lift off entire indicator post head.
- Turn operating stem nut in closing direction until target carrier becomes disengaged.
- Remove TRUARC retaining ring IP–4, using a pair of TRUARC field pliers, number 2600, external type.
- Lift operating stem nut out of body.
- To install operating stem nut, reverse above procedure.
