Features & Benefits

Output Torque 300 in-lb (34 Nm) to 18,000 in-lb (2,034 Nm)
Decades of Bray’s proven success in electric actuation, combined with innovative engineering, has produced the Series 70 electric actuator. The Series 70 features on/off or modulating control and offers many advantages over other actuators including:
  • UL, CSA and CE certification of most units
  • Wiring directly to the terminal strip without interference from other components
  • Simple and unique manual override handwheel system
  • Lowest profile and lightest weight actuator on the market
  • Simple finger or screwdriver adjustment of travel limit cams without interference from other components
  • Highly visible valve status display on most units (Heartbeat)
Series 70 Design Features
Designed like a junction box, the Series 70 offers by far the easiest access to terminal block wiring, cam adjustments and switch installation. Therefore, the time required for field startup and adjustment is greatly reduced, and maintenance can be performed with assured ease and safety.
