The ProMation Engineering fail safe electric actuator can operate when power is lost, now with Class/Div (CSA & ATEX) options available. These actuators are ideally suited for when automatic valve control must be managed and controlled after the power is out, and where flow must be maintained or operated quickly and efficiently for safety.
ProMation Engineering has two distinct lines of fail-safe solutions to protect lives and processes.
– Mechanical – Spring Return Actuators (PA Series) (D Series)
– Electrical – Battery Back-up for All Actuators (PBU Series)
