A piercing valve is a valve with a pointed sharp tip that is used to gain access to a sealed refrigeration system that does not have service valves or Schroeder ports. And is to be used as a temporary device .
Bicycle tube valves are one-way valves. They let air pass one way, then holds it in.
Read the tube! No. Body piercing is considered a deep puncture wound.
They were called thermionic valves. there was also the cathode ray tube (CRT)
That's a strange question. When you say valve I think about bike tire tube valves. These you generally get with the tubes. The only tube for which valves are regularly replaced are the ones with Dunlop valves, which are pretty rare outside Scandinavia. Then there are tubeless tire systems, but for a valve for those you turn to the rim/tire manufacturer.
Valves, tuning slide, and spit valves.
There are three primary types of inner tube valves: Schrader, Presta, and Dunlop. Schrader valves are commonly found on car tires and have a wider diameter with a spring-loaded mechanism. Presta valves are narrower, typically used on high-performance bicycles, and require a threaded nut to secure them. Dunlop valves, less common, are similar to Presta but have a larger diameter and are often found on some European bicycles.
No, you cannot use a Presta tube on a Schrader rim because the valve types are not compatible. Presta valves are thinner and require a smaller hole in the rim, while Schrader valves are wider and require a larger hole.
WCC in tube valves typically stands for "Welded Carbon Steel." This designation indicates that the valve is constructed from carbon steel and is designed for welded connections, making it suitable for high-pressure and high-temperature applications. WCC valves are commonly used in various industrial processes where durability and strength are essential.

Instead of valves, trombones have a movable slide. When extending the slide it causes the tube to be longer and this impacts along with lip configuration to changing the note and pitch
There are two main types of valves used in bike inner tubes: Presta and Schrader valves. Presta valves are thinner and require a smaller hole in the rim, while Schrader valves are thicker and more commonly found on car tires. The type of valve can affect the ease of inflation and the compatibility with different pumps. Overall, the valve type does not significantly impact the performance of the tube itself, but it can affect convenience and compatibility with different equipment.
The choice between TR6 and TR4 inner tube valves depends on the specific application and personal preference. TR6 valves are typically longer and offer better accessibility for inflating tires, making them ideal for certain vehicles or setups. Conversely, TR4 valves are shorter and may be preferred for tighter fitments. Ultimately, the decision hinges on the rim design and the user's needs for convenience and functionality.
