Product Overview
The AUMA SA Series is a multi-turn electric valve actuator designed for open-close and positioning duty on gate valves, globe valves, and similar multi-turn valve types. It provides dependable torque transmission, accurate limit and torque switching, and spans a torque range from 10 Nm to 32,000 Nm for different valve sizes and process conditions.
SA-type actuators for open-close duty carry Class A and B ratings or short-time duty S2 – 15 min. An optional version supports longer running times (S2 – 30 min). These actuators pair with various actuator controls, from basic OPEN-CLOSE units to micro-controlled versions featuring operating data logging or a fieldbus interface.
Limit and torque sensing come standard. Motor options include 3-phase AC, 1-phase AC, and DC. A handwheel allows manual operation. The IP68 enclosure per EN 60529 delivers high-quality corrosion protection (KS) and handles ambient temperatures from -30°C to +70°C. Output drive types meet DIN and ISO standards.

Application Industry
The AUMA SA Series is used in water and wastewater treatment, power generation, oil and gas, petrochemical, chemical processing, district heating, and industrial plants. It handles open-close duty on gate valves, globe valves, and other multi-turn valve applications. The IP68 enclosure makes it suitable for harsh outdoor or submerged conditions.
Common Problems
No reaction to operation commands: Check movement at actuator. Verify the reaction time setting. Check for mechanical blockage or power supply issues.
Torque fault in OPEN or CLOSE direction: Check for valve obstruction. Verify torque switch settings. Inspect for excessive valve friction.
Mechanical position indicator cannot be set: Reduction gearing is not suitable for the turns/stroke of the actuator. Exchange reduction gearing.
Actuator runs to end stop although limit switches work properly: Check limit switch settings and end position configuration.
Motor winding temperature too high: Check actuator sizing. Verify the duty cycle matches the application. Correct sizing if necessary.
Replacement Models
The AUMA SA Series is a current-generation multi-turn electric actuator platform. The SAR Series is a modulating actuator variant rated for Class C or duty type S4 – 25%. The SAEx Series is available for explosion-proof applications (torque range 10 Nm to 16,000 Nm). The SA-UW Series is designed for continuous underwater use (torque range 10 Nm to 4,000 Nm). For cross-vendor alternatives, verify valve mounting, torque requirements, and control interface compatibility before ordering.
