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).
