Simply... the valve is a one way valve that lets in air one way but does not let air out. It it basically a hole with a flap on the inside. The flap closes when pressure is pushing out but opens when pressure is pushing in.. like when you put in the pump nozzle.
At Loch Ness, click the left side of the truck, then click and hold the valve stem (arrow) until enough air escapes.
solenoid valve function is to hold or handle the flow of gas or liquid pressure
I think it is like 4-6 pounds or something :)
Buy a new basketball.
The air in a basketball lets the basketball bounce.
if you are asking about the air valve on the tire to add/let out air then it is a schrader valve or an American valve
Hold the valve stem until enough air has gotten out of the tire.

The shocks have a air valve just like a tire valve, just take the cap off the valve and depress the insert in the valve to let air out.
a basketball is kinda like a ballon if it has to much air it pops
At Loch Ness, the driver's trailer is too high to go under the bridge. Let some air out of the tires to lower it. Click on the left tire, then click and hold the valve stem until enough air gets out.
