The American Water Works Association (AWWA) is responsible for setting standards on the design, performance and manufacturing of valves and associated equipment. With over 50,000 members, it is the world’s largest scientific and educational association dedicated to managing and treating water.
Rotork Gears has launched its IB AWWA series of bevel gearboxes, designed specifically for the manual operation of AWWA standard C560 cast iron and C561 fabricated stainless steel gate valves.
Developed from the successful and rugged Rotork IB multi-turn gearbox range, the AWWA series feature a fully sealed cast or SG iron enclosure that is grease filled for life and certified as watertight to IP68 as standard. Precision engineered input pinion and output bevel gears with low friction hub bearings provide an extended service life and smooth operation under high load conditions. Output flanges, to MSS SP-102 or equivalent ISO and DIN standard dimensions, feature a removable output sleeve to facilitate easy valve adaption. The standard operating temperature range is -40º to +250ºF (-40 to +121ºC), with other temperature ranges available on request.
