Dwyer Instruments MGO-4T | Gear operator | Works with 8" size BFV Series butterfly valves | Min. output torque 4425 in-lbs. (500 N m) | Max. output torque 6196 in-lbs. (700 N m)
Heavy-duty on-off or throttling service for valves or dampers, such as our BFV Series butterfly valves, is provided by the Model MGO-4T Gear Operators. These gear operators operate smoothly and without issues because they are self-lubricating. Weatherproof, the tough cast iron body has O-ring body seals. The valve is held in the desired position by a self-locking worm and worm gear. A hand wheel that is easily accessible, a valve position indicator, and mechanical travel stops that allow field adjustment for valve movement to certain degrees of rotation are among the features.
