1 IW Quarter-turn Gear Series The IW series of quadrant worm operators has been designed with customer stocking in mind, and features a removable steel output sleeve to facilitate bore and keyway machining. This separate output sleeve can be positioned through 90º steps on the IW3 & through 5º steps on the IW to IW11. The baseplate can be positioned through 5º steps on the IW3 to and through 22.5º steps on the IW to. This facility allows for on or off centre mounting on the valve spool without special machining. Operating temperature normally ranges from -0 to +120 ºC, although other temperature ranges are available on request. Standard input (for actuation purposes) and output flanges are to ISO 5211 standard. However, equivalent standards such as MSS & DIN can be supplied. Application Rotork Gears IW series operators are quarter-turn devices intended for the operation of ball, plug and butterfly valves as well as power and process dampers. The gearboxes are suitable for manual and motorised applications. Features Totally enclosed gearing Grease filled for life and fully sealed Comprehensive gear ratios combined with a selection of auxiliary input spur gear reducers Angular contact bearings supporting worm shaft Removable output sleeve Repositionable baseplate facility Adjustable mechanical stops (at 0º and 90º ±5º) Environmental Specification IW Quarter-turn Gearboxes Enclosure: IP7 standard suitable for submerged duty up to a depth of 1 metre for 30 minutes Temperature: -0 to +120 ºC (-0 to +250 ºF) Options Ductile Iron IP8 AWWA, ATEX, Nuclear All types of environment High temperature range -20 to +150 ºC (- to +302 ºF) Extra high temperature range -20 to + ºC (- to ºF) Low temperature range -0 to +120 ºC (-7 to +250 ºF) Padlockable handwheels Limit switches Lever arms Travelling nut for applications requiring less than 90º travel and more than 90º Modulating and multi-turn Input flanges for motorisation Flexible extensions Firesafe to ISO 1097 Interlock safety system Enclosure IP8 suitable for submerged duty up to a depth of 15 metres for 72 hours CS type suitable for continuous submerged duty up to a maximum depth of 15 metres Keeping the World Flowing
