Double-helix transmission converts piston motion into shaft rotation, combining rotary drive, load support and holding for valves, indexing, tilting, clamping and heavy-duty rotation.
Front or rear flange mounting for valves, indexing and compact rotary mechanisms.
Foot-supported design for tilting, clamping and base-mounted equipment.
Flange or foot mounting for large valves, mining and metallurgical equipment and heavy-duty rotation.
| Series | Model range | Mounting | Standard rotation | Drive torque, kN·m | Typical applications |
|---|---|---|---|---|---|
| XRF | XRF02-XRF28 | Front / rear flange | 180°; selected models 360° | 0.192-2.825 | Valves, indexing, compact rotation |
| XRT | XRT05-XRT44 | Foot mount | 180° | 0.509-4.407 | Tilting, clamping, heavy-duty support |
| XRH | XRH19-XRH429 | Flange or foot mount | 180°; selected models 360° | 1.921-42.94 | Large valves, mining/metallurgy and heavy rotation |
Drive torque varies approximately with actual A/B port differential pressure. Torque, radial, axial and overturning loads must be evaluated as a combined load case.
Hydraulic locks hold position; bidirectional counterbalance valves control overrunning loads and loss-of-pressure risks.
Mechanical indicators, proximity or limit switches and position sensors can be integrated with valve blocks and speed control.
Running, breakaway and peak torque; rotation, travel time, pressure, flow, combined loads, flange and output interfaces.
Includes all three series, displacement, weight, dimensions, model codes, installation, commissioning, maintenance and ordering data.
