NIHON KOSO CO.
Nihon Koso Solid State Electronic Actuators
Manufacturer: NIHON KOSO CO., LTD.
Features
- Each product of this series drives and controls a control valve, with a motor driven by a full-electronic controller upon receipt of a signal (4 to 20 m ADC) from the controller.
- A product of 3500 series, which is of high-end type, executes critical control by means of a brushless DC servo, a product of 3600 series or 3620 series providing superior cost performance executes control by an AC reversible motor. Furthermore, a product of 3620 series, which is of motor built-in type, provides excellent heat radiation effect.
- In addition, explosion-proofing approved models are also replete.
