Type of valve
Replacing a valve stem.
A valve stem is a self-contained valve that opens to admit gas to a chamber (such as air to inflate a tire ),[ 1] and is then automatically closed and kept sealed by the pressure in the chamber, or a spring ,[ 2] [ 3] or both, to prevent the gas from escaping.[ 4]
There are many types of valves, and they are most commonly used on automobile , motorcycle , and bicycle tires , but also for many other applications. The most common type is the Schrader valve , but some road bicycles with skinny tires instead use the Presta valve .[ 5] [ 6] [ 7] [ 8]
