• 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.
