DIGITAL VALVE POSITIONER : SEL (Linear Type)
Features
- Auto-calibration for optimum zero and span setting
- Simple and easy to set
- Precise control performance and high dynamic response
- Pressure regulator built in to eliminate variations in supply air pressure
- Low air consumption due to piezo electric microvalve
- Input/output signal isolated
- Automatic detection for DA(direct acting) or RA(reverse acting)
- Single and double acting available
- No hunting on the small actuators
- 1/2 split range available
- High resistance against shock and vibration
Option
- Position transmitter (4…20㎃ output signal)
- 2 X alarm limit (open, close)
- Explosion proof type (Exd IIB T6, Exia IIC T6)
