GEAR OPERATORS
All gear operators are lubricated for life at assembly, prior to shipment from factory.
During installation, customer should carefully adjust gear operators to suit the valve
OPEN and SHUT positions; no further attention is normally required throughout the
product life.
For installations where spare parts are held on site, it is suggested that a spare gear
operator be held as an interchangeable item. In the event of gear operator suffering
damage or excessive wear in service, it is recommended that a replacement be
supplied.
For any technical enquiries please call NIBCO Technical Services.
