WCC mean standard temp.
Bicycle tube valves are one-way valves. They let air pass one way, then holds it in.
hello ...if u study a216 ..u can find 3 grades..wca,wcb and wcc..there are different based in diferernt alloy material and tensile strength and diferent percent of carbon....wcc>wcb>wca

They were called thermionic valves. there was also the cathode ray tube (CRT)

since there are so many valves, and they are rotory valves, there are actual tubes for each valve, including a valve for the trigger and a valve for no buttons as well. there are not as many valves on the trumpet because they have a different type of valves: the valves of the trumpet work like when you press down the button, the actual valve moves and a hole opens so it shows that the button was pushed down so the pitch comes through. there is only one necessary tube on the trumpet, because the valves are just holes in the tube. this is different on horn, because there are different tubes for each valve. the horn valves are rotors, so when you press down the button, the rotor moves and opens a hole. there is a different rotor for each valve, which means that every valve MUST have its own tube. this is why there are so many tubes on the horn:]

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.
WCC steel is a high grade cast plain carbon steel. It is of a higher grade, quality, and price than WCB steel.
Valves, tuning slide, and spit valves.
It means "atrioventricular". It refers to the valves between the atria and the ventricles.
