CPR-1 Series Compact Pressure Regulator

General Details

The CPR-1 Series is a Compact Pressure Regulator with most of the same internal design features employed in our time proven PR-1 series. This regulator was designed to provide optimum performance as a “lecture bottle regulator” for pressure control in any application where a small size and low internal volume are required. The low internal volume allows more rapid purging in analytical instrumentation and semiconductor doping gas applications.

  • Gas or liquid service
  • 316L stainless steel construction
  • Internal volume is less than 3cc
  • Electropolished body with better than 25 Ra finish in diaphragm cavity
  • 20 micron inlet filter
  • Bubble tight shutoff
  • Outlet pressure ranges are 10, 25, 50, 100, 250 and 500 psig
  • Proof pressure is 2 times maximum working pressure
  • Burst pressure is 4 times maximum working pressure
  • Weight: 1.1 lbs (0.50 kg)
  • Mounting style is surface or panel (see Outline and mounting dimensions)
