The CPR-1 Series is a compact pressure regulator with most of the same interanl desigm features employed in our time proven PR-1 Series. This regulator was designed to provide optimum performance as a "lecture bottel" regulator" for pressure control in any application where a small size and low internal volume are required. The low volume allows more rapid purging in analytical instrumentaion and semiconductor doping gas applications.

Features & Specifications
  • Internal dead volume less than 4cc
  • Gas or liquid service
  • Inlet pressures of up to 6000 psi
  • Adjustable outlet pressure ranges of 0 - 10, 0 - 25, 0 - 50, 0 - 100, 0 - 250, 0 - 500 and 0 - 750 psig
  • Operating temperatures of - 40º F up to +500º F (-40º C up to +260º C)
  • Bubble-tight shutoff
  • Cv flow coefficients 0.025, 0.06, and 0.20
