Mechanical variable speed drive - 1:1 - 5:1 | VR series

The VR Series - Dry Friction Speed Variators are used in fractional and medium power drives and general purpose applications. The fully sealed enclosure with the dry friction enables a maintenance-free, reliable and safe installation. It is designed in 4 sizes with its covers and housings made of die cast aluminum for sizes 63 and 71 but of cast iron for sizes 80 and 90. The variators are equipped with output flanges. These variators are compliant with standard IEC sizes to fit the different worm/wheel and helical units.

Valve actuator gear reducer - 125 - 1 000 Nm | GHE series

This range GHE is suited for part-turn butterfly valves and ball valves that are ideally suited for ship-building.

Despite high levels of automation, there is still a need for valves that are manually operated, such as when the corresponding valve can only be opened or closed infrequently.
