Construction allows servicing without removing from the line
وصف
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.
