The Schrader valve is used on virtually all automobile tires and motorcycle tires and most wider-rimmed bicycle tires.In addition to tube and tubeless tires, Schrader valves of varying diameters are used on many refrigeration and air conditioning systems to allow servicing, including recharging with refrigerant; by plumbers conducting leak-down pressure tests on pipe installations; as a ...
Tubeless tire technology does away with the need for an inner tube thereby increasing safety. [1] [4] [citation needed] In a tubeless tire, the tire and the rim of the wheel form an airtight seal, with the valve being directly mounted on the rim. If a tubeless tire gets a small puncture, air escapes only through the hole, leading to a gentle ...
In episode 13 of Gabe’s Bike Shop, Gabe compares Presta and Schrader valves, presents cyclists with holiday gift ideas, and talks tube preference.
Schrader valves use a spring to close, so Schrader chucks use a "pin" to open the valve while the chuck is attached. This avoids the Presta's nut, but leads to use of slower screw-on or heavier clamp-on Schrader chucks. Presta valves are mainly used on bicycles, and are rarely used on cheaper bicycles. Presta pumps are thus less common.
By 1891 he had produced the Schrader valve, which was his most popular invention and is still used today on many bicycle tires and almost all automobile, truck, and motorcycle tires. August's son, George, is generally credited with the experimental work that resulted in the valve's creation. In 1893, Schrader patented the tire valve cap.

The Dunlop valve, (also called a Woods valve, an English valve or a Blitz valve [1]) is a type of pneumatic valve stem in use—mostly on inner tubes of bicycles—in many countries, including Japan, [2] Korea, India, Pakistan, Sri Lanka, most European countries, and a number of developing countries.
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.
