RWS series part-turn worm gearbox is designed base on RW series, and developed for large torque, manual and automatic valve. The first stage transmission of this series is using worm gear to drive, second stage transmission is using worm gear or bevel gear to drive. There are tapered roller bearings with high performance installed on both ends of the first stage worm shaft, it can bear double-directional thrust while withstand radial forces, and also the bearing clearance can be adjusted. Therefore, under large torque, long life.Because of the selectable double-stage input structure, rotatable angle of mounting hole between output end cap and housing, users can flexibly choose installation angle according to installation conditions.

1. Totally enclosed gearing with good sealing
2. Ductile cast iron housing, reliable strength
3. Grease filled, increase the service life
4. Optional input structure, flexible input mode
5. Optional ratio of double-stage gearbox, used in a wide range
6. Adjustable angle of output end cap, flexible modes of installation
7. Optional output flange type
8. High performance of tapered roller bearing, can withstand axial and also radial forces
9. Sealed structure, good waterproof effect, can be up to IP68 if required
10. Adjustable stopper, 0 °and 90 °(±5 °adjustable)

RWS series part-turn worm gearbox is suitable for dampers, ball valve, butterfly valve and other 90 °rotary (quarter- turn) valves.

Operating Environment
