AUMA MDE 71-2/60 Electric Valve Actuator | Flameproof 

The AUMA MDE 71-2/60 Electric Actuator is a heavy-duty motorized unit built for high-performance valve automation in hazardous areas. It features an explosion-proof design compliant with EEx d IIC T4 standards, making it suitable for use in environments with explosive gases. The actuator carries a PTB-certified explosion protection rating (PTB Nr. Ex 80/1071 U) and is engineered to ensure operational reliability in demanding conditions. With a 4.6A current rating and robust build, it is ideal for oil and gas, chemical, and petrochemical industries. Inspected in May 1987, this actuator remains a reliable choice for legacy systems.
