Chinese Globe Valve Body AUMA SA Multi-turn Electric Control Valve Actuators with LE Linear Thrust Units
The AUMA SA 07.2 – SA 16.2 multi-turn actuators combined with LE 12.1 – LE 200.1 linear thrust units form a robust electric actuation system for converting rotary torque into linear thrust on valves requiring stem extension/retraction. These actuators deliver adjustable torque from 10 Nm to 1,000 Nm across a wide speed range, suitable for open-close duty in industrial valve applications. The linear thrust units enable precise axial force up to 360 kN over strokes from 50 mm to 500 mm. Designed for 3-phase AC motors, the system ensures reliable operation in demanding environments, with self-locking gears and customizable configurations for rising or non-rising stems.
- Versatile torque and speed options with adjustable tripping for OPEN/CLOSE directions.
- Self-locking design up to 90 rpm (50 Hz) for secure positioning without backdrive.
- Compatible with EN ISO 5210 and DIN 3210 valve attachments for easy integration.
- Robust handwheel reduction for manual override.
- High thrust conversion efficiency with factors from 2.6 to 4.6.
- Suitable for non-rising stems with max diameters up to 100 mm.

- Gate and globe valves in water treatment and pipelines.
- Chemical processing plants for linear motion control.
- Power generation for boiler feedwater valves.
- Oil & gas for wellhead and choke valves.
- General automation requiring thrust conversion from rotary actuators.
- How do I select the right LE unit? Match thrust requirements and stroke to actuator torque using the conversion factor (e.g., 2.6 for LE 12.1).
- Is self-locking always active? Yes for speeds ≤90 rpm (50 Hz); higher speeds are not self-locking.
- What valve stems are supported? Rising stems with LH thread (e.g., M12 x 1.25 to M42 x 3); non-rising on request.
- Can I use for modulating duty? Use SAR versions for S4/S5 duty; SA for open-close only.
- How to calculate thrust from torque? Use formula F = T / f, where f is the factor (e.g., 0.15 adhesion assumed).
