AUMA SEVEN variable-speed multi-turn electric actuator, 9–4,000 Nm

AUMA SEVEN is a variable-speed multi-turn electric actuator: soft unseating and seating of the valve with faster travel in mid-stroke. This reduces water hammer and seat wear. Open-close duty and precise positioning, torque 9–4,000 Nm.

The AUMA range also includes SAV (10–1,000 Nm, open-close) and SARV (15–1,000 Nm, modulating); SEVEN is the alternative for higher torque. Exact speeds, enclosure protection and temperature range are given in the data sheet of the selected size.

Key features:

• Variable travel speed
• Soft unseating and seating — less water hammer and seat wear
• Torque 9–4,000 Nm
• Alternative to SAV/SARV for higher torque

Specifications:

• Type: multi-turn, variable speed
• Duty: open-close and precise positioning
• Torque: 9–4,000 Nm
• Speed: variable, depends on size
• Communication: via AUMA actuator controls
• Enclosure protection, temperature: per size specification

Application: Gate and globe valves where travel speed must be varied and water hammer limited.

Scope of supply: Actuator of the selected size, handwheel, AUMA electrical connector. Actuator controls, fieldbus, mounting bracket and gearbox per data sheet.

Before ordering: Speeds, enclosure protection and temperature range are confirmed per data sheet of the selected size. Before ordering, specify the valve type, torque, stroke and required speed profile.
