    Features & Benefits

    		 N/A
  • 18 turn non-rotating stem
  • Low internal volume provides low flow control
  • Non-rotating stem minimizes unwanted variability of flow rate
  • Unique thread design allows tapered needle portion of the stem to be withdrawn into the outer stem
  • O-ring seals below the stem threads provide smooth operation and eliminate backlash
  • Panel mounting is standard for all models
  • Dial indicator provides repeatable positioning of stem in full turns and tenths of a turn from closed to fully open.
  • Position by finger tip rotating the knurled aluminum dial.
  • A position lock prevents accidental movement of the handle and resulting errors in flow data.
  • The size and design of the handle assembly provide an attractive appearance for equipment panels.
