The Pro-Gear Series “X” quarter turn gearboxes are very light weighted, but rugged industrial grade products, made of a high pressure casted aluminium housing. All models in this series feature high performance bearings and a powder coated finish.


The X series is highly suitable for all general industrial applications as well as applications in chemical, power, HVAC and waterwork. Pro-Gear’s operators are intended for the operation of ball, plug and butterfly valves as well as power and process dampers. The usage of high grade, but very light materials provides a tough, reliable and very light weighted unit for the automation of today’s high performance industrial valves.
