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 ...
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.
A tubeless tire (also spelled as tubeless tyre in Commonwealth English) is a pneumatic tire that does not require a separate inner tube.. Unlike pneumatic tires which use a separate inner tube, tubeless tires have continuous ribs molded integrally into the bead of the tire that are forced by air pressure into a flange on the metal rim of the wheel, sealing the tire to the rim.
Presta valves (also called Sclaverand valves or French valves) are normally only used on bicycles. The stem has a narrower diameter (nominally 6 mm) than the thinnest (nominally 8 mm) Schrader type, and so the bore of the hole in the rim through which the stem passes can be smaller. Has a locknut that needs to be opened to inflate/deflate. [17 ...
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.
A modified Schrader valve - with a floater - is used in self-acting vents on the very top of pipes. Via Schrader valves cooling medium is filled into the air conditioning of cars, small powder fire extinguishers are filled with nitrogen or pressure-checked. --Helium4 08:47, 8 August 2010 (UTC)
Around 1890, after reports of English cyclists' success using pneumatic tires, August Schrader saw the need for a bicycle tire valve. By 1891 he had produced the Schrader valve, which was his most popular invention and is used today. August's son, George, is generally credited with the experimental work that resulted in the valve's creation.
