Rotork extends established range of manual bevel valve gearboxes

The Rotork Gears Hand Operated Bevel HOB3 gearbox extends the scope of the established HOB/MPR bevel gearbox range.

The Rotork Gears Hand Operated Bevel HOB3 gearbox is a new addition to the well-established HOB/MPR range of bevel gearboxes, designed to offer robust, reliable and cost effective manual operation of gate valves, globe valves and penstocks.

The single ratio HOB3 design extends the scope of the range for the operation of smaller valves, such as 100 mm to 300 mm (4˝ to 12˝) gate valves. F10 to F16 baseplate options with stem diameter acceptance up to 40 mm offer maximium flexibility for valve adaptation.

Manufactured with a cast iron gearcase, ductile iron baseplate, protected steel input shaft and fasteners, the HOB3 has been life- tested to ensure that maximum performance, reliability and quality is consistently maintained. The totally enclosed, maintenance-free gearing is grease filled for life and environmentally sealed to IP67.

The HOB3 maximum torque output is 315 Nm, with 75 kN maximum thrust. The standard ambient operating temperature range is -40 to +120°C, with high and low temperature options available. Further options include increasing the IP67 watertight enclosure to IP68, padlockable input, local position indicator, cover tubes, special coatings for aggressive environments and a firesafe trim conforming to ISO 10497.

The HOB3 is available with a complete range of mounting brackets, extension shafts, pedestals and accessories to suit any valve application, whilst the Rotork worldwide network of offices and representatives provides a local source for sales, service and support for all Rotork Gears products.
