Valve actuator

JX-05M series


Pursuing usability and safety

[JX-05M] model super small valve actuator is an electric operation device developed for small-diameter glove and gate valves.
As a pioneer in valve actuators, it is an actuator designed using our long and rich experience to meet our clients’ needs.
As a result of pursuing usability and safety, the hand wheel is equipped as standard, and the mechanism of switching from manual mode to electric mode has an automatic restoration function.


  • Automatic restoration

    As a result of pursuing handling quality and safety, we adopted the declutch lever for switching to manual mode and an automatic restoration function for switching to electric mode.
    After switching to manual mode with the declutch lever and operating the hand wheel, it is not needed to return to electric mode.
    Activating the motor restores to electric mode automatically.

  • The worm gear system is used.

    A simple structure using a worm gear as the power transmission mechanism.
    Using a worm gear ensures self-locking in both the electric and manual modes.

  • The worm gear is made of high-strength bronze.

  • For weight waving, the housing is made of aluminum alloy.

  • Microswitches are used for torque and limit switches. They are safe because the live part is not exposed.

  • The intermittent gear prevents the limit switch from deviating from the setting.
