Limitorque B320 SeriesBevel Gear OperatorsRugged and dependable for manualor motorized valve control applicationsExperience In Motion
B320 bevel gear operators provide mechanical advantagefor multi-turn actuation applicationsThe Flowserve Limitorque B320 bevel gear operator notonly makes it easy to manually operate multi-turn valves— it also makes it easy to convert to motorized service.Limitorque offers the B320 in an extended array of standardsizes and configurations to cover the widest range of applications, with the most common units are in stock for2immediate shipment. Limitorque also accommodatesspecialized needs with a variety of options, includinghandwheels, chainwheels, spur gears, and operating wrenchnuts. Like every Limitorque product, the B320 is backed byFlowserve’s worldwide service and parts supply network.
flowserve.comB320 features: built for reliable valve control —whether manual or motorizedThe B320 offers torque ranges up to 8,000 ft-lb (10,856 N m)and thrust capacities to 325,000 lb (1445 kN), for anyapplication demanding a bevel gear operator with superiorstrength and accuracy. It is most commonly used withsluice/slide gates, gate valves, and globe valves.Easily adaptable for other applicationsFlowserve Limitorque has designed the B320 to be configuredto each customer’s needs. Choose an optional handwheelfor manual actuation. Add a spur gear attachment for greatermechanical advantage. And when manual operation simplyisn’t practical, just couple the B320 with one of Limitorque’selectric actuators for an economical, motorized, multi-turnpackage.Available options for the B320 operator include:Spur gearattachments forreduction ofinput torqueHandwheelsand chainwheelsDirect mountingto an electricvalve actuator3
Solid construction inside and outAll B320 series operators are manufactured from the highestquality materials for maximum reliability. All gears are machinedfrom high-strength alloy steel, ensuring smooth operation withminimum backlash. Input and output bevel gears — as well asthe bevel pinion itself — are supported on low-friction rollerbearings. Every B320 operator is permanently lubricated and fullywaterproof to endure the harshest outdoor service. B320 seriesoperators are suitable for weatherproof (NEMA 4) or temporarysubmergence service (NEMA 6, IP 67/68). All units are easilyconverted for motorized applications.Bevel pinion and bevel gears are completelysupported on anti-friction ball bearings.4
