Advantates
- It can remotely control dampers and machinery even under adverse conditions such as high altitude, high temperature, and dust generation.
-
Because of its easy maintenance management and high durability, it has been used for a long time in industrial fields such as iron and steel, cement, nonferrous metals, and electric power. There is a track record of 30 to 40 years of use if overhauled .
Features of Damper Actuator:
Select from 4 types of control units
- S type – 4 ON-OFF contact function
Position signal: 2 contacts each for fully open and fully closed
Torque signal: 2 contacts each for fully open and fully closed
Opening transmitter: None
- R type – Mounted Potentiometer:
Position signal: 2 contacts each for fully open and fully closed
Torque signal: 2 contacts each for fully open and fully closed
Opening transmitter: Potentiometer
- F type – Current Transmitter:
Position signal: 2 contacts each for fully open and fully closed
Torque signal: 2 contacts each for fully open and fully closed
Opening transmitter: Current transmitter
- Y type – Synchro transmitter:
Position signal: 2 contacts each for fully open and fully closed
Torque signal: 2 contacts each for fully open and fully closed
Opening transmitter: Synchro transmitter
- Options:
We also manufacture a model with a built-in inverter positioner that automatically operates based on the customer’s opening command (4 to 20 mA DC). (Output torque 200N・m to 4000N・m limited)
Other features:
- High reduction ratio: The reducer is a compact actuator that is composed of three types of reduction mechanisms: planetary gears, worm gears, and eccentric gears, achieving a reduction ratio of approximately 1/3600.
- Equipped with overload detection mechanism as standard: Safe design that detects overload torque and stops the motor before it is damaged.
-
Equipped with manual handle as standard: Even in emergencies where electricity cannot be supplied, such as power outage, the damper can be moved and controlled using the included manual handle.
Operating principle
The motor’s power is reduced to approximately 1/3600 by a reducer, producing a large torque that moves damper.
When damper reaches fully open or fully closed position, built-in limit switch automatically stops the motor.
It is also possible to install a transmitter. You can check the opening status in real time.
How to use?
- Determine mounting position:
Due to restrictions on heat resistance of operating motor, control equipment, lubricating oil, etc., ambient temperature should preferably be 40°C or less, and should not exceed 45°C at the most. - Mounting:
When connecting output shaft and load shaft, align and install them so that midpoint of their operating angles match. Turn manual handle so that indication on indicator scale plate is at 45 degrees, and then connect when it matches middle position of load shaft. - Wiring:
Please check interconnection diagram and wiring diagram of panel before wiring. - Adjustment:
After checking wiring, check motor rotation direction so that it can be stopped at any time. Cam is adjusted before shipping, but adjustments are required if the cam is fully open or fully closed or if transmitter position is not correct. Please adjust according to instruction manual.

Regular maintenance recommended
The damper actuator has several lubrication points, so please lubricate it regularly. Please refer to instruction manual for the types and timing of lubrication and lubrication.
