SMART VALVE POSITIONER : SSL (Linear Type)

Smartest valve control device meeting a dynamic performance and a precise setting with a piezoelectric technology and an optimized auto-calibration program

Features

- Auto-calibration for optimum conditions
- Precise control performance and high dynamic response
- Easy operation with fork-key pads and full text graphical LCD
- Single and double acting
- Low air consumption due to piezo electric microvalve
- Pressure regulator built-in to eliminate variations in supply air pressure
- Problem-free characteristics on a small actuator
- High resistance against shock and vibration
- Mounting on linear actuators according to IEC 534

 

Option 

- Position transmitter (4…20㎃ output signal)
- 2 X alarm limit (Min.,Max.)
- Explosion proof type (Exd IIB T6, Exia IIC T6)
- HART communication (FSK)
