About this item

  • Control sensitivity of .125" (.32) water column allows use in precision applications
  • Balanced supply valve minimizes effects of vacuum variation
  • Aspirator tube compensates for downstream pressure droop under flow conditions
  • Separate control chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing
  • Construction allows servicing without removing from the line


P3RA171 is a high accuracy vacuum regulator that provides uniform vacuum regulation independent of vacuum supply changes and full demand. This unit is a true vacuum regulator and does not control vacuum by letting air into the system. This regulator should be mounted between the vacuum source and process itself. A vacuum regulator unit has a diaphragm assembly with three springs to provide a more balanced loading of the diaphragm. A separate control chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing.
