AUMA’s TIGRON SIL is the winner of this year’s Primus Award in the Actuators category. The award ceremony took place at DIAM exhibition in Bochum, Germany, on 12 November 2025.

The SIL version of TIGRON is AUMA’s new high-performance, explosion-proof electric actuator series for safety-related applications up to SIL 3. It combines maximum safety with outstanding configuration flexibility, providing solutions even for highly complex safety requirements.

Up to four different safety functions can be configured within the same actuator and can be parametrised in any priority. Additional parameters such as type of seating in the end position can also be customised to meet specific customer needs. Thanks to a timer function, TIGRON SIL can slow down shortly before reaching the valve end position, effectively preventing pressure surges in the pipeline.

The SIL version of AUMA’s TIGRON thus provides solutions even for highly complex requirements in safety-related systems. TIGRON SIL is certified for the safety functions Safe ESD OPEN and Safe ESD CLOSE (both with and without timer function), Safe Stop, and Safe end position feedback OPEN and CLOSE. The safety functions are controlled and monitored by safety-related firmware. The safety-relevant part of the TIGRON SIL was developed and evaluated in accordance with IEC 61508:2010 (SIL) and ISO 13849 (PL) and is certified by TÜV Nord. SIL 3 can be achieved with a redundant system setup.

In addition to the comprehensive safety-related features, TIGRON SIL users benefit from all the core advantages of AUMA’s successful TIGRON series. Offering outstanding IIC explosion protection, TIGRON is ideally suited for hydrogen applications. The compact and powerful all-rounder is reliable, durable, and withstands the toughest operating conditions. TIGRON is available with a broad range of modern interfaces, including Profinet, offering easy and flexible integration into all common control systems. In addition, seamless data exchange with CORALINK, AUMA’s digital ecosystem, simplifies predictive maintenance.

The Primus Award is given by German valve industry magazine ‘Industriearmaturen+Dichtungstechnik’ in cooperation with the DIAM & DDM German valve industry exhibition. Its three prizes honour the most innovative products in actuators, valves, and seals, respectively.
