[JX-05M]
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.
Features
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.
Optional features
Outline
There are two proven methods of operating an actuator even in the case of a power outage: The method in which a DC motor is used, and the method in which an air motor is used. Historically, DC motor-type actuators have been used for emergency isolation valves in many power plants, as well as water supply and sewerage systems.
Matters to be noted as the requirements for DC motors
1. High starting torque characteristics appropriate for valve characteristics 2. Motors to which the line starting method is applicable Because the motors to which the line starting method is applicable do not require current-limiting resistance at the time of starting nor a switching circuit, which are required for general-purpose DC motors, the circuit can be simplified.
