Model RADAB RA 14.3:


Multi-turn Actuator with Positioner:


This product can be operated both manually and electrically. This product includes open/close limit switches, adjustable and programmable torque switches, and an automatic clutch system to open/close and control industrial valves. Installed positioners have an output current limit of 4-20 mA. In the RA series actuators, open-close and positioning duties are done by an S2-15 min motor. It is also possible to attach a suitable PID controller to the product to accomplish a more complex control function.


Advantages of the RADAB actuators:


  • Limit switches can be adjusted digitally.
  • Torque switches can be adjusted digitally.
  • Limit and torque sensing ability.
  • Having an OLED monitor to show the opening/closing percentage of the valve and the amount of torque applied to the valve.
  • Suitable for all types of industrial valves.
  • A remote-control capability is available.
