CW Series

• Housing material options (carbon steel / stainless steel)• Worm wheel material option available in aluminum bronze• High temperature variant up to +200°C (+392°F) & low

temperature variant up to -52°C (-61.6°F) available• Marine application (all exposed shafts and fasteners in

stainless steel) • IP-67 standard enclosure (IP-68 available on request)• Chainwheel material is ductile iron and chain guard is carbon

steel. Both are powder coated• Chain is in carbon steel (zinc plated) with option in stainless

steel

FeaturesDescription

• Gearbox series designed for chainwheel operation• Design based on IS-EA series and adopts all features of this

series• 27 models up to a torque of 325,000 Nm and F-60 mounting

base• Ductile iron casing and alloy steel worm shafts• Angular contact bearings to handle high loads and higher speed• All models have optimized lengths of input shafts supported

in bearings so as to minimize the cantilever load of the chain wheel, chain guard and chain

• Widely used on valves for oil and gas, chemical, power, waterworks, sewage, gas pipelines, HVAC, etc.

• Epoxy primer coating is standard

• Top mounted / top operated version (“handwheel, chainwheel or electric actuator” to be mounted / operated from the top of the gearbox and not from the side) of AT-IS, CW and IS-EA series (all models)

• Twin-shaft version available for some models of AT and AT-IS series to reduce no. of turns to close for manual operation (for models above AT-300/2/S3 and AT-300/1/S3-IS)

• Stainless steel version of gearboxes available for applications in highly corrosive environments as well as food and beverage, pharmaceutical and sanitary facilities. Option available for all models of AT, AT-IS, IS-EA and CW series

• Gearbox options as per API 6D specifications available for torques up to 3500 Nm• Part turn 180° operated gearbox option available up to 15000 Nm
