AUMA SA/LE linear electric actuator, thrust 4–217 kN

AUMA SA/LE combines the SA multi-turn electric actuator with the LE linear thrust unit: rotation of the output shaft is converted into linear stem travel. It is used on globe valves and control valves that need a straight stroke rather than a rotating nut.

Thrust 4–217 kN. Stroke, speed and stem connection are defined by the LE size; duty, enclosure protection and explosion protection follow the base SA actuator. A compact low-thrust alternative is SDL/SDG, 2–15 kN; a linear version is also available in the PROFOX-L platform.

Key features:

• Thrust 4–217 kN
• Combination of SA multi-turn actuator and LE linear unit
• For globe and control valves with rising stem
• IP68 and KS corrosion protection of the base actuator

Specifications:

• Type: linear, SA + LE combination
• Thrust: 4–217 kN
• Duty: as base SA actuator
• Stroke, speed, stem connection: depends on LE size
• Enclosure protection: IP68 of the base actuator
• Corrosion protection: KS of the base actuator
• Ambient temperature: −30…+70 °C
• Explosion protection: as base actuator
• Communication: via actuator controls

Application: Globe valves and control valves with linear stem travel.

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

Before ordering: Before ordering, specify the required thrust, stroke and stem connection, stroke time, supply voltage and need for explosion protection.
