RParker Standard High Precision Vacuum Regulators | P3RA171 Series


 p3ra171-high-precision-vacuum-regulator		 The P3RA171 is a high accuracy vacuum regulator that provides uniform vacuum regulation independent of vacuum supply changes and flow demand. This unit has a diaphragm assembly with three springs to provide a more balanced loading of the diaphragm.

FEATURES

  • 1/4" ports (NPT)
  • Control sensitivity of .125" water column variation for use in precision applications
  • Balanced supply valve minimizes effects of vacuum variation
  • Aspirator tube compensates for downstream pressure drop under flow conditions
  • Separate control chamber isolates diaphragm from the main flow
  • Unit construction allows you to service without removing from the line
