Light duty pressed stainless steel quarter turn gearboxes suited for pharmaceutical, wash down and corrosive environments.

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. These 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.
