Enclosure
- Polyester powder-coated aluminum alloy
- NEMA type 4X, IP66 & IP67, intended for outdoor use
- ISO 12944-2 corrosivity category C3. C4/C5 is optional.
Motor
- Insulation class F
- Built-in thermal protector prevents the motor from overheating and burnout.
- Thermal trip temperature:
AC motor: 125±5℃ (257±9℉)
DC motor: 90±5℃ (194±9℉)
Duty Cycle
- 30% duty cycle
- The extended duty option is not applicable.
Position Indication
- A mechanical position indicator is located on the top of the actuator.
Manual Override
- The non-clutch design allows for manual operation without needing a lever, clutch, or brake when the power goes out.
- When the electric motor is operating, the hand-wheel will not rotate to ensure personal safety.
Gear Train
- High-alloy steel planetary gears are used, and a self-locking function is provided.
- The gears are lubricated for life with high-temperature grease.

Anti-condensation Heater
The heater warms actuators to prevent lubricant freezing and moisture damage.
● Not recommended if the ambient temperature exceeds 35˚C (95˚F).
● For large day/night or seasonal temperature variations, use with a thermostat is recommended.
Heater Thermostat
Heater thermostat switches of f the heater when the internal temperature of actuators is higher than 25±5˚C (77±9˚F).
Auxiliary Limit Switches
Actuators come standard with two limit switches, LS1 for fully-open and LS2 for fully-closed positioning. Two auxiliary limit switches (LS3 & LS4) are optional for fully-open and fully-closed position feedback.
Analog Output
Recommended to use with a floating control actuator for position indication.
● Analog output: 0-20 mA, 4-20 mA, 0-5 V, 0-10 V, 1-5 V, and 2-10 V.
＊ This image shows the 110/220V AC version.
Modulating Control
A proportional control unit, including analog input (AI), analog output (AO), and a 5kΩ potentiometer.
● Analog input: 4-20 mA, 1-5 V, and 2-10 V
● Analog output: 4-20 mA and 2-10 V
＊ This image shows the 110/220V AC version.
Potentiometer
Recommended to use with a floating control actuator to output signal for position indication.
● Two resistance values, 1k ohm or 5k ohm for selection.
Local Control Unit (LCU)
Two rotary selector switches are provided, LOCAL/REMOTE and CLOSE/OFF/OPEN. In LOCAL mode, the valves are directly being controlled in the field and can be operated to close, stop or open by using CLOSE/OFF/OPEN selector switch.
● Standard: IP65
● Optional: IP67
● Three phase power supply units with modulating control must be optioned with LCU.
Torque Switches
The torque switch option protects the actuator from overload. When preset torque is reached, the switch stops operation to prevent damage.
● It must be ordered with the actuator and is factory‑installed, calibrated, and tested.
Chain Wheel Drive
To allow manual operation in high, hard-to reach locations by means of a slight pull on the sprocket chain.
Junction Box
Junction box enables external electrical connection to be done without removing actuator cover.
Isolation Relay Module
When using one control switch to operate two or more actuators, the isolation relay module is recommended.
Communication Protocol
Modbus RTU RS485
● Suitable for 110–120V AC and 220–240V AC, with 30% duty cycle.
Stainless Steel Enclosure
SS316 (CF8M) enclosure
● IP68 (7m, 72 hrs)
＊ For outline dimensional drawing of SS316 enclosure, please contact your salesperson.
IP68 Protection Rating
● IP 68 (7m, 72 hrs), according to EN 60529.
