Man­ual gear oper­a­tors for quar­ter-turn valves

DEMM Engineering & Manufacturing - - PRODUCT WATCH -

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.
