Features and Benefits

  • Ten turn micrometer dial calibrated in 1% increments, with the ability to adjust capacity from 10% to 100%
  • Variable Oil By-Pass™ Stroke Adjustment provides a better valve performance when compared to variable linkage designs
  • Bright color contrasted dial protected from corrosion by clear PVC covering
  • Stroke mechanism moves only when adjustment is made, eliminating wear
  • Piston is powered through complete stroke length at all capacity adjustments, eliminating stress, wear and shock of lost motion designs
  • Totally enclosed fan-cooled motor with built-in automatic thermal overload
