Nucom Series: Modulating, Control actuators

Does your application call for severe control? The Koei Nucom actuator provides 250-400 steps over 90 degrees, no overrun, no hunting. Linear actuators provide this precision over the entire stroke. Measure that up against the control you feel you are getting from your control valve. 4-20 mA input and output signal eliminates need for external positioning devices. By the unique Built in Motor Construction, the ADC Body works as Motor Heat Sink, which ensures high frequency start-stop motion without getting overheated. Nucom is born to be applied for continuous process control catching up 100% for your PID signals.

Unic Series: On/Off electric actuators

Sharing the same body and power train as Nucom, the Unic model is naturally over-spec. for just on-off. Its IP65 housing is made of Aluminum Die Cast with the electric motor built in structure making a small, compact and lightweight actuator with powerful torque output. Torque ranges: 10-1950 Nm. Thrust 35-1200 Kg force. The palm sized Unic Z/05 is suitable for small butterfly and ball valves. The largest Unic-200 weighs only 22 Kg, is 38 x 25 x 18 cm in dimension, and generates more than 1900Nm with no secondary reduction required.
