Key:valves

The tag valves=* is used to map valve stems for air filling stations found at gas stations (compressed_air=yes), bike repair stands (service:bicycle:pump=yes), or dedicated air filling locations (amenity=compressed_air). Valve stems are essential components for inflating tires, and understanding the types available at these locations can help users ensure compatibility with their vehicles or bicycles.

Types of Valve Stems

Name	Description	Value	Image
Schrader	Code: AV. The Schrader valve / Car valve is commonly found on cars, motorcycles, and many bicycles. It is a robust valve design with a wider opening, which makes it easier to use with high-volume air pumps. The valve consists of a threaded stem into which a valve core is inserted and can be opened or closed by depressing a central pin.	valves=schrader	Schrader Valve
Sclaverand	Code: SV. The Sclaverand / Presta valve / French valve is typically found on high-performance bicycles, especially road bikes and some mountain bikes. It is a thinner valve compared to the Schrader and is known for its ability to handle higher air pressures.	valves=sclaverand	Sclaverand Valve
Dunlop	Code: DV or NV. The Dunlop valve, also known as the Woods valve, is common in Europe and Asia on bicycle tires. It shares similarities with both the Schrader and Presta valves but has a unique design that allows it to maintain pressure even at lower levels.	valves=dunlop	Dunlop Valve
Regina	Code: RV. The Regina valve is now a rare valve type and is mainly found in older European bicycles, mostly in Italy. It is similar to the Schrader valve in design but requires specific adapters for inflation.	valves=regina	Regina Valve
