IW Quarter-turn Gearboxes

Transcription

1 IW Quarter-turn Gearboxes 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 45º steps on the IW4 to IW11. The baseplate can be positioned through 45º steps on the IW3 to IW5 and through 22.5º steps on the IW6 to IW12. This facility allows for on or off centre mounting on the valve stool without special machining. Operating temperature normally ranges from -40 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 & IN 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.
