INSTALLATION, OPERATION AND MAINTENANCE MANUAL
MODEL
RB
WEIR GATES
MAINTENANCE: CLEANING AND LUBRICATION
Orbinox model RB weir gates need practically no maintenance. In order to assure maximum per-
formance of the weir gate, the following maintenance inspections shall be carried out periodically
(every 6 months):
Stem and stem nut shall be cleaned and greased. In some configurations, the stem may be in
contact with water and dirt. Under these conditions, the threads of the stem and/or stem nut may
wear, and they shall be checked every 3 months.
Clean the gate with clear water and remove any deposits, especially on the seals and in the
guides.
Check the seals and make sure they are not damaged. Seals shall be replaced if damaged. See
section „Maintenance: Seal Replacement‟ for detailed procedures about seal replacement.
Seals shall be wet while operating. If the weir gate has not been used for a long period of time
under dry conditions, the seals shall be wetted with clear water before operating the weir gate.
Operating the gate with dry seals may damage the seals. Additionally, more torque may be re-
quired to operate the weir gate.
Spare parts:
Orbinox does not recommend stocking any spare parts by the owner of the equipment as the weir
gates are designed for a very long life cycle. If a repair part is required, please contact an Orbinox
representative and provide the following information:
Orbinox S/O number.
“Orbinox General Arrangement Drawing” number.
Project name (if applicable).
