Pro-Gear’s “K” and “R” series are designed for the operation of multiple turn valves and dampers and are sealed according to IP68. All models are manufactured with cast iron housing components, and, as per our standard, all models feature high performance axial bearings, a stainless steel input shaft and a polyurethane coating. Additionally, the “K” and “R” series both fully conform to AWWA specifications.

Applications

The Pro-Gear “K” and “R” series are bevel gearboxes and spur gearboxes with totally enclosed spindles and gearing and are sealed according to IP68. All models feature a polyurethane coated finish, high performance axial bearings and stainless steel input shaft. The bronze drive sleeve is easily removable for machining, enabling customisation to suit the valve stem. For all manually operated gate, globe, knife gate valves and isolation dampers in industries such as HVAC, Power, Chemical and Water & Waste, Pro-Gear’s “K” and “R” range provide a very suitable and reliable solution. As an option, Pro-Gear can offer clients output flanges according ISO standards for motorisation.

Performance specifications

Performance specifications

The Pro-Gear Series “QSS” quarter turn gearboxes are rugged, industrial products, manufactured with a stainless steel 316 housing. All models in this series feature aluminium bronze (AB2) quadrants, as well as teflon coated high performance bearings.

All other main components which are exposed to a corrosive environment, such as the inputshaft, the position indicator and the studnuts, are also made from stainless steel 316.

Applications

The QSS series is highly suitable for all applications in highly corrosive environments such as pharmaceutical plants, chemical plants, off-shore industries and marine services.
The QSS series are intended for the operation of ball, plug and butterfly valves as well as power and process dampers. The usage of high grade materials provides a though, reliable and highly corrosive resistant unit for the automation of valves in today’s highly demanding industries.
The handwheels which allow a smooth operation are available in a variety of sizes and are made of stainless steel 316 only. This QSS series is also applicable with several other applications such as padlocking devices, limitswitchboxes and memory stops.

Performance specifications

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.

Applications

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.

Performance specifications

The Pro-Gear Series “Q-LT “ quarter turn gearboxes are rugged, industrial grade products, manufactured with ductile cast iron housing and components. All models in this series feature high performance bearings and a powder coated finish

Applications

The Q-LT series is highly suitable for all low temparature industrial applications as well as low temparature applications in chemical and power plants. 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 of materials provides a tough, reliable unit for the automation of today’s high performance industrial valves. Several options such as padlocking devices, memory stops, spur gears and limit switchboxes can be eassily mounted on site without any machining, due to the inte­gration of all necessary connections on the housing.
