Installation, Operation and Maintenance Manual
XXXXXXXX Rev. 1
The ATB Series gearbox is used to operate a gate valve, globe valve, pinch valve or used in
reduction applications. The torque is transmitted through the hand wheel and bevel pinion
which in turn, drives the adaptor located in the bevel gear thereby multiplying the torque
transmitted from bevel pinion to the bevel gear, which is connected to the valve stem.
The purpose of this IOM is to help the user of this equipment on the following:
• Safety instructions
• Installation of ATB Series gearboxes
• Operation of ATB Series gearboxes
• Maintenance of ATB Series gearboxes
