Product Overview
The Dwyer MGO-3T is part of the Series MGO range of manual gear operators for heavy-duty valve and damper applications. This model is specifically sized for 6" BFV Series butterfly valves and provides reliable manual actuation for both on-off and throttling service.
The operator delivers an output torque range of 1328 to 2930 in-lbs (150 to 270 N·m) and uses a 24:1 gear ratio with a mechanical advantage of 6.72. This combination provides the mechanical leverage required for manually operating compatible butterfly valves.
The MGO-3T features a rugged cast iron housing with O-ring body seals and is designed for weatherproof indoor or outdoor installation. Its self-lubricated construction supports smooth, trouble-free operation while reducing the need for routine lubrication.
A self-locking worm and worm gear holds the valve in the selected position without drifting. The readily accessible hand wheel provides manual control, while the integrated valve position indicator allows the operator to identify the valve position during operation.
Mechanical travel stops can be adjusted in the field to control the valve's degrees of rotation. This makes the MGO-3T useful where specific valve opening positions are required for throttling or process control.
For proper sizing, the required valve torque should be divided by the gear operator's 6.72 mechanical advantage to determine the required input torque. The input torque can then be divided by the hand wheel radius to determine the required hand wheel rim effort.

How to Specify & Commission It
- Confirm that the MGO-3T is compatible with the 6" BFV Series butterfly valve and that its torque capacity meets the valve's requirements.
- Divide the valve's required torque by the 6.72 mechanical advantage to determine the required input torque.
- Divide the input torque by the hand wheel radius to determine the required hand wheel rim effort.
- Mount the gear operator to the valve stem according to the manufacturer's installation instructions.
- Adjust the mechanical travel stops to provide the required degrees of valve rotation.
- Operate the valve using the hand wheel and confirm the valve position using the integrated position indicator.
