NT Series Electro-Pneumatic Positioner
Features
- Precise Control: Receives 4~20mA DC current signal from a controller to precisely control valve position via pneumatic actuator.
- Versatile Action: Direct and Reverse action, as well as Single and Double acting modes, can be easily switched without replacing parts.
- Economic: Low air consumption design.
- Split Range: Supports 1/2 split range control without replacing internal parts.
- Compact Design: Small structure suitable for connecting small actuators; features anti-vibration design.
