ROTORK Gears reports that international markets have reacted positively to the introduction of its range of 242 Series manual gear operators.
Significant activity in China includes an important order from valve manufacturer China Valves Hanwei for a natural gas project. The 242 Series manual quarter-turn gear operators feature the latest design technology for robustness and durability as well as minimal non-structural mass and reduced size.
Suitable for operation of ball, butterfly and plug valves or other quarter-turn devices in most general industrial applications, all 242 Series units have a 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 to deliver an output torque range of up to 2100Nm. Built with standard ISO base dimensions between F05 and F25, the 242 Series is said to be ideally suited for low-torque manual applications.
