New gear­box for mo­torised quar­ter-turn ap­pli­ca­tions

DEMM Engineering & Manufacturing - - PRODUCT WATCH -­quiry #160306

The lat­est ad­di­tion to the mar­ket-lead­ing range of gear­boxes man­u­fac­tured by Ro­tork Gears is a rugged, in­dus­trial grade prod­uct de­signed for use with mo­torised quar­ter-turn valves and dampers.

The new AB550M gear­box is man­u­fac­tured as stan­dard with cast iron hous­ing com­po­nents, high per­for­mance ax­ial thrust bear­ings, a pro­tected steel in­put shaft and a polyurethane coat­ing to deal with ar­du­ous ap­pli­ca­tions and ag­gres­sive en­vi­ron­ments. The abil­ity to sup­port elec­tric ac­tu­a­tors weigh­ing up to 46 kilo­grams and in­put speeds of up to 72rpm of­fers suit­abil­ity for many ap­pli­ca­tions in the chem­i­cal, power gen­er­a­tion, wa­ter and sewage treat­ment, HVAC and gen­eral in­dus­tries.

With a max­i­mum out­put torque of 600 Nm, 45mm max­i­mum out­put bore, out­put f lange sizes from F07 to F16 and +/-5˚ ad­justable 90˚ stroke, the AB550M will op­er­ate a large range of ball, but­terf ly and plug valves, or power and process dampers.

The am­bi­ent op­er­at­ing tem­per­a­ture range can ex­tend from -60˚C to +200˚C, whilst the stan­dard IP67 en­vi­ron­men­tal pro­tec­tion can be in­creased to IP68 for marine, con­tin­u­ous sub­mer­sion and buried ser­vice du­ties. A fire­safe op­tion con­form­ing to ISO10497 is also avail­able.
