Gear operators

The gear operators are robust in construction and the materials are suitably selected to ensure a high product performance. The worm wheel is made of SG iron/phosphor bronze that enables high torque transmission. The worm is made of alloy steel having adequate strength thereby achieving lesser input-torque. The design of worm and worm wheel pair ensures self-locking. Adjustable stopper bolts are provided for precise valve positioning. Technical specifications: Gear Box: BOKM41 Operation: manual Output torque for manual operation (kg-m): 12 Mounting PCD: 78 Mounting holes x size: 4 x M10 Maximum value of shaft diameter: 24.75 mm Recommended maximum hand wheel diameter: 160 mm Number of turn for 90 degrees: 10 Total reduction ratio: 40:1 Features: To increase the operating torque range a secondary unit is provided with spur gear attachments and accessories Additional features include hand wheel, chain wheel, declutching arrangement, limit switch and electric actuators A pilot hole is provided on the housing to enable easy filling of lubricant Gearboxes are supplied with IP 54 enclosure (dust proof) and under special cases gearboxes can be supplied with IP 68 enclosure Efficiency in turning the valve disc from open to close and vice-versa by 90 degrees Conveniently designed for both manual and motorised control for mechanism requiring 90-degree operation. Adaptability to suit either manual or motorised operation by means of simple modification The mounting flange on the gearbox is designed to suit ISO 5210 or Din 3210 standards
