ABSTRACT:
A solenoid valve that is to be used to control flow of a liquid medium is tested in a test fixture which applies a leak test, a flow test, and a response test using a gas as a test medium. The test results are compared with a test specification that has been previously derived from an established correlation of tests using gas as a test medium versus liquid as a test medium. The invention enables the valves to be tested with gas instead of liquid.
