Tracer Gas Fill Valve
The step tests the gas fill valve for internal leakage by registering pressure rise behind
the valve.
Possible results:
• No Internal Leakage
• Internal Leakage
Internal leakage can result in:
• Erroneous pressure decay results
• False vacuum decay rejects increased gas consumption
Test Port 2 Valve
This step tests Test Port 2 valve for internal leakage by registering pressure rise behind
the valve.
Possible results:
• No Internal Leakage
• Internal Leakage
Internal leakage can result in:
• False blockage test accepts
