ESA.EXC series – Explosion-proof electric rotary actuators (35 to 8,000 Nm)
Maximum performance and explosion protection
The explosion-proof electric rotary actuators of the ESA.EXC series have been designed for safe operation in potentially explosive industrial environments. They cover a wide torque range from 35 to 8,000 Nm and are ideally suited to the automation of ball valves and butterfly valves in sensitive areas.
Certified to the highest safety standards: with comprehensive certifications in accordance with ATEX and IECEx (Ex db IIC T4/T5/T6 Gb and Ex tb IIIC), these actuators ensure uncompromising safety in gas and dust explosion-hazard zones. Thanks to an intelligent design featuring an integrated display, on-site/remote control, configurable end positions and an integrated ESD (Emergency Shutdown) function, they offer full control and maximum reliability in critical processes.
