  • Standard: 1/2 ” NPT
  • Optional: 3/4” NPT、M20、M25
  •  

Manual override :

  • Non-clutch design, requires no lever, clutch or brake for manual operation.
  • When the electric motor is operating, for personal safety the hand-wheel won’t rotate.
  •  

Operating direction :

  • The spring return direction cannot be changed. The spring return direction must be configured by the manufacturer, Please select the fail action according to the required application, i.e. based on clockwise or counterclockwise operation.
  • Standard: Fail clockwise spring return.
  • Optional: Fail counter-clockwise spring return.

  • Space heater

    A space heater can increase the internal temperature and keep dry inside actuator to avoid the freezing lubricant and moisture causing actuator failure under low temperature or high humidity. Heater is not recommended if the ambient temperature is above 35℃/95℉. However, when the temperature varies much from day to night or between summer and winter, heater and thermostat (25±5℃/77±9℉) are recommended.

  • Heater thermostat

    The option can switch the heater off when the temperature inside the actuator is over 25℃/77℉.

  • Additional limit switches

    The standard model equips with the 1st & 2nd switches for fully-open and fully-closed. The option consists of the 3rd & 4th auxiliary switches which provide dry contacts for fully-open and fully-closed.

     

  • Current position transmitter

    The option can provide 4-20mA output signal and suit for two-position control units.

    The picture is based on AC 110/220V

  • Floating controller

    The actuator can be controlled by external controller to open, close and stop at any position between 0 and 90 degree and will fail clockwise to the end position on loss of power. (Based on the standard running direction that the actuator fails clockwise on loss of power.)

    The picture is based on AC 110/220V

  • Modulating controller

    Actuator can be operated according to input signal and provide the output signal for feedback. Input signal：4-20mA，1-5V，2-10V Output signal：4-20mA，2-10V

    The picture is based on AC 110/220V

  • Operating direction

    Standard : Fail clockwise on loss of power.

    Optional : Fail counter-clockwise on loss of power.

     

  • Manual override

     

  • Potentiometer unit (1K or 5K)

    The option can be ordered with two-position control actuators. The selection has 1k or 5k ohm resistance values. It provides feedback signal for position indicator.
