Valve Explanations
1. Valve Body
- Valve Body
- Valve Insert
- Valve Cap
The rubber valve for tubeless tires is designed to seal air-tight in the hole in the rim. The elastic material of the rubber body presses itself tightly into the hole in the rim.
When valves with threaded metal feet are used, a rubber seal is used to seal the rim. The area around the edge of the valve hole is a sealing area. Therefore, they must be free of rust, dirt and damage.
2. Valve Insert
The valve insert has the most important job in the valve. It creates a seal and enables the regulation of the air pressure. The small plate seal on the valve core can only do its job when it is free of impurities, dirt and moisture. The compressed air system must be free of water and oil!
3. Valve Cap
A valve cap must always be screwed onto the valves. It prevents dirt from getting into the valve. Dirt which may be in the valve would reach the seal of the valve plate when the tire is inflated and cause a leak.
The valve must be replaced every time a new tire is fitted.
If the vehicle is driven without caps on the valves, there is the danger that dirt may get into the valve. This leads to gradual loss of air and therefore lead to the destruction of the tire:
- Separation of shell and rubber
- Wide circumferential grooves in the bead area.
- Torn-out tread or protector.
No air-tight seal due to an incorrectly tightened valve cap.
- Install the valve cap firmly on the valve.
Do not screw any aluminum valve caps onto steel valve bodies. Aluminum caps attach to the steel valve body into a inseparable connection and cannot be separated again.
