Rotork Gears

Rotork Gears refers to the gear operator and manual drive product families within Rotork plc, the Bath-based valve actuation group founded in 1957. Rotork's gear heritage includes the historic K-Gear range of part-turn and multi-turn gearboxes, which long predates the company's electric actuator fame and remains in service on waterworks, pipeline and power station valves across the world. The gear range provides manual worm gear operators for quarter-turn valves — ball, butterfly and plug — and bevel or spur gear units for multi-turn gate and globe valves, sized for torque capacities from small plant valves to the largest pipeline spheres, with IP-rated sealing for buried service and corrosion-protected castings for offshore duty. Gearboxes are engineered to interface cleanly with Rotork actuators, allowing semi-automatic packages where the gear manual override remains available during power loss. Combined with Rotork's fluid power and electric ranges, the gear line lets a project standardize drive solutions on a single supplier.
