Valve Cores

A Schrader® valve consists of a hollow cylindrical metal tube, typically brass, with the exterior end threaded. The interior end form varied depending on the application of the valve. In the center of the exterior end is a metal pin pointing along the axis of the tube; the pin's end is approximately flush with the end of the valve body.

There are a number of options for customers wishing to purchase valve cores in both the OEM and aftermarket sectors, see the product part tables below for more information.

Most Schrader® valves used on tires have threads and bodies with a standard exterior size allowing for universal caps and tools whether the tire is on an automobile, bicycle or even a wheelbarrow or lawnmower. A Schrader® valve can be used to control: Air, nitrogen, R12, R22, R134a, oils, Halon, SF6, Petrols, butane, propane.

The valve core is made up of 3 main pieces:

The bridge for screwing the valve core into its housing.
The seat with its joint providing a static seal from the valve body.
The valve with its spring for introducing or draining fluid and guaranteeing sealing under pressure in the rest position.

Construction information:

Materials: Brass, stainless steel, elastomer
Joint: Polychloroprene, Nitrile-butadine, Hydrogenated nitrile-butadine, Fluorocarbon, EDPM
Body finish: Rough, Enamelled, Enamelled copper plate

Valve cores are defined by their characteristics, and depending on the type selected, these characteristics vary depending on the material, the finish and the design of each valve core.

Detachment pressure: This is the air pressure necessary to overcome the resistance of the spring that keeps the valve closed, allowing air to pass through.
Opening pressure: This is the pressure necessary to open the valve significantly, causing a significant debit to pass through the valve core.
Debit : It is measured in the direction of the air loss under a pressure of 7 bars, the valve being open to the max. The air is then put back under normal conditions.
Min. travel: This is the valve opening travel necessary to allow the min. air debit necessary for a pressure measurement, for example.
Max. travel: (valid only for short valve cores with spring above the bridge). This is the valve opening travel not to be exceeded to avoid damaging the valve core
