Rotork Gears extends established range of manual bevel valve gearboxes

摘要

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.
