Manual gear operators for quarter-turn valves
The 242 Series manual quarter-turn gear operators from Rotork Gears division from the latest design technologies to provide optimum robustness and durability with minimal nonstructural mass and reduced overall size.
Suitable for the operation of ball, butterfly and plug valves or other quarter-turn devices in most general industrial applications, all 242 Series manual gear operators feature a sturdy cast iron IP67 watertight enclosure, a ductile iron wormwheel, PTFE thrust washers and adjustable end stop screws.
A range of five sizes is available to accept valve stem diameters of up to 70mm (or 58mm square section) and deliver an output torque range of up to 2100Nm.
Built with standard ISO base dimensions between F05 and F25, simple and rugged 242 Series gear operators are ideally suited for low torque manual applications. Options include stainless steel input shafts and fasteners, Namur and Westlock mountings, an IP68 temporarily submersible enclosure and a padlock kit.
A rendered CAD image of the 242 has been selected by Siemens for the Solid Edge ST5 design software splash screen and will appear in rotation whenever users around the world start using Solid Edge ST5.
