ST-6 SmarTrak

ST-6

The intelligent valve positioner ST-6 series receives the 4~20mA DC currentsignal from the control room or signal  generator and other current output devices, adjusts the air pressure input to the valve actuator,and precisely adjusts the valve opening according to the proportion.

Plus

  • LCD screen (LCD) and four buttons
  • Quick and easy automatic setting
  • Partial itinerary test function ( PST)
  • Fault alarm function
  • Built-in automatic/manual switch knob
  • self-diagnostic function
  • IP66/NEMA4X protection class
  • The large flow lead valve is used to speed up the valve action
  • Impact resistant, seismic design
