The latest Rotork Gears ABAW AWWA worm gear operators are designed in accordance with AWWA (American Water Works Association) specifications C504 and C517, which are the AWWA design specifications for manually operated butterfly and plug valves respectively. The AWWA is responsible for setting standards on the design, performance and manufacturing of valves and associated equipment for managing and treating water.
One of the first orders, from a world-leading valve manufacturer, is for 160 gearboxes encompassing the full ABAW size range, for above and below ground applications in the North American water utilities market.
Manufactured from robust, high quality materials, ABAW gearboxes are designed to meet or exceed all aspects of AWWA C504 and C517 design specifications. The fully sealed, grease filled enclosure with self-lubricating sleeve bearings facilitates long term reliable service within a standard temperature range of -20 to +120ºC (-4 to +250ºF). High and low temperature options are also available.
Other options include stem extensions, square nut inputs, padlock kits, NAMUR and Westlock position indicator mounting kits and open right configuration (input shaft turns clockwise to open valve). Overload capabilities of up to 450 ft. lbs. above rated torque outputs exceed AWWA specifications for preventing gearbox damage from excessive applied torque, delivering the robustness required for long term reliability.
