Smile my pneumatic selinoid valve not switching

hello,

i need help on my newly ordered pneumatic solenoid valve, i am trying to test it but it does not seem to switch when i apply the 12 volt. i can hear the sound of some kind of relay but the coil is probably not energized. what am i doing wrong ? the valve is from wic it is rated for 12 volt. my intention is to use a darlington transistor to drive it, but i can not go to that stage before i make sure that it work in its basic configuration by directly energizing it


regards
mohammed

Is this 12 volt dc valve? What amperage? Does your power supply match in voltage and equal or exceed the required amperage. If valve is DC is it a DC power supply?

A car battery or something smaller? Have you tried blowing through it while energized?

What is "wic". I assume you didn't get this from the nutrition program for Women, Infants, and Children.

yes it is a bit smaller 12 v battery than that of a car, i triedw to brow through it hoping the path will change to the other port but it did not. WIC is the brand or the manufacture.

The specs seem to indicate a minimum pressure of 27PSI so I'm not sure you can test by blowing.

i think there is what i am making the mistake, i am not considering the pressure parameter and my lungs are not that powerful

thank you for the insight.
