SM/H — Stepper motor hydraulic actuator
The SM stepper motor actuator has an internal mechanism which is arranged to be interfaced to the female thread of the threaded stem valve actuation. Two hydraulic or pneumatic actuators allow to manage the rotation of the internal mechanism of the stepper motor, one clockwise and the other anticlockwise, thus obtaining the rotation in fixed steps of the nut screw and the linear movement of the threaded rod. These actuators are available in different sizes, in order to reach different torques.
- Internal mechanism: 15 step / run
- Operating pressure: from 4 bar to 10 bar (air) / from 70 bar to 250 bar (oil)
- Operating temperature: -20°C to +70°C (lower and higher temperature available on request)
- Output torque: up to 400 Nm
- Standard supply medium: oil, instrument air
- Stroke: up to 4” (100 mm)
- Special executions on request
