Slab Gate Valve WCB/LCB Gear Operator Aluminum - Bronze Worm Gear
SB series multi-turn gear operators
This gear operator series is made of cast steel and the optional material is HT. Bronze, D2 and QT nuts are available to fit in with the valve stem. This series is suitable for use on linear-motion valves including gate valves and globe valves, with the single-stage speed ratio varying from 2.3:1 to 8:1 and the torque from 216NM to 6800NM.
Instructions for Installation and Operation
Connect the bottom flange of the gear operator to the upper flange of the valve and slide the valve shaft into the drive nut. Tighten the flange bolt. The valve can be closed by turning the hand-wheel clockwise and opened by turning the hand-wheel counterclockwise.
