Wilkerson WRA171 Series
High Precision Vacuum Regulator
The WRA171 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
• Control sensitivity of .125" (.32 cm) water column allows use in precision applications.
• Balanced supply valve minimizes effects of vacuum variation.
• Aspirator tube compensates for downstream pressure droop under fl ow conditions.
• Separate control chamber isolates the diaphragm from the main fl ow to eliminate hunting and buzzing.
• Construction allows servicing without removing from the line.
