AUMA Valve Alternative

AUMA Riester GmbH & Co. KG

AUMA (Müllheim, Baden-Württemberg, Germany) is Europe's leading electric valve actuator manufacturer, widely specified in water treatment, power generation, oil & gas, and chemical plants. AUMA's SA (multi-turn) and SGR/GS (part-turn/bevel gear) actuator ranges are found globally on gate valves, globe valves, butterfly valves, and ball valves. Vajra Industrial Solutions supplies equivalent electric actuator packages with the same ISO 5210/5211 mounting interface at competitive pricing for new projects and retrofit applications.

Legal DisclaimerAUMA, SA, SAR, SGEx, and AM are registered trademarks of AUMA Riester GmbH & Co. KG. Vajra Industrial Solutions is not affiliated with AUMA. We supply independently sourced actuators to equivalent specifications.

Why Consider AUMA Alternatives?

AUMA's premium European pricing makes them uncompetitive for Indian and developing-market projects

Equivalent ISO 5210/5211 mounting allows seamless substitution on most valve types

Faster lead time from India — 6–10 weeks versus AUMA's typical 14–18 week delivery from Germany

Replacement/maintenance procurement when AUMA spare parts have long lead times

AUMA → Vajra Equivalence Reference

Indicative equivalences for common AUMA valve series. Dimensional and specification compatibility must be verified by the project engineer before substitution.
