300 Quarter-turn Gear Series

The Rotork Gears Series ‘300’ quarter-turn gear operators are the first of their kind to use metal forming technology in their manufacture. This technology dramatically reduces manufacturing costs and allows the

operator to be produced from stainless steel.

Application

Rotork Gears series ‘300’ operators are quarter-turn devices intended for the operation of ball, plug and butterfly valves as well as power and process dampers. The unique sintered steel drive insert allows these gear

operators to be fitted directly to most valve stems. The handwheels are available in a variety of sizes for smooth and easy operation.

The stainless steel operators are well suited for applications in highly corrosive environments as well as in breweries, pharmaceutical plants and sanitary facilities.
