SS5 Smart Valve Positioner

Brand: A-T Controls, Inc.
Perfect combination with reliable fail freeze function and smart performance with innovative durable coil drive.
Features
  • “Fail Freeze” function to help the valve stay at the last position on the electrical power supply or the pneumatic supply air by accident 
  • Easy and quick auto-calibration 
  • Detects RA (reverse acting) or DA (direct acting) automatically regardless of wrong air connections 
  • Available to use for single or double acting without any special adjustments 
  • Compact design allows installation on small actuator 
  • Provides error messages against performance failures 
  • Possible to test the actuator with any fixed signal under a test model 
  • Programmable characteristic curve with 17 points 
  • Wide operating temperature range -30° to 80° C (-22 to 176° F) 
  • Improved control of high-friction globe and ball valves by eliminating an overshoot and a hunting 
  • Low air consumption 
  • Provides a mounting bracket to meet IEC 60534-6-1 for linear valves 
  • Supports a NAMUR mounting pattern VDI/VDE 3845 (IEC 60534-6-2) and provides a multi-size mounting bracket for rotary valves
