Test Data
Reverse Bias Leakage
Time series reverse bias leakage testing was performed on the 3002-06-01 valve to quantify reverse bias leakage at low reverse bias psid. The leakage was plotted over time due to the tight leakage requirements of the valve.
Test Sensor: 10 SCCM (0.60 SCIM) full scale output Alicat flow meter
Test Media: Ultra High Purity grade GN2
Pressure Drop
Pressure drop testing was performed on the 3002-06-01 valve to quantify pressure loss across the valve for various low flow rates. Since check valves must overcome crack pressure to begin flowing, a check valves full ESEOD is not reached until higher flows are achieved.
Test Sensor: 500 SLPM full scale output Alicat flow meter
Flow Media: Ultra High Purity grade GN2
