Q:24 valve V-6 vs. 12 valve V-6?
The 24 valve has 2 intake and 2 exhaust valves when the 12 valve only has 1 intake and exhaust per cylinder, the 24 would give u more power but will most likely use more gas.
Q:inner tube valve (Specialized) too large for the hole in rim (Bontrager)?
There are two kinds of valves used on bicycles. The large one, the Schrader valve, is the same as the valve used on cars. The thinner one is the Presta valve. The only possible way to get into the situation you describe is to have a Schrader valve tube and a Presta valve rim. Take the tube back to where you bought it and exchange it for a Presta valve tube. Presta valves are easy to operate. To inflate them, remove the plastic cap if one is there. Fully loosen the fitting at the top of the valve. It will not come off. Inflate the tire to recommended pressure with a Presta valve pump, a pump that automatically does both valve types, or a threaded adapter that will let you use a Schrader valve pump (remove the adapter when done). Then, screw down the fitting that you loosened to start. You really don't need the plastic cap. Their purpose is the keep the valve from puncturing the tube when the whole thing is folded up. Once you've installed the tube in the tire you don't need the cap any more. HTH EDIT: (sorry for shouting) DO NOT DRILL OUT THE RIM! That has the potential for serious safety problems.
Q:Can I take a reversing valve from a heat pump.?
it depends on the unit but you can run it without the heat pump..somtimes its the solenoid and not the actual valve body that can be replaced without recharging.check the current to the valve first.
Q:Is valve standard of API and ISO same?
This Site Might Help You. RE: Is valve standard of API and ISO same? what's the differences of American standard valve standard and Europe valve standard. Like API598 and ISO5208 , EN12266 valve inspection standard, or API600 valve design manufacture standard,and EN598,
Q:Bike tire valve cost?
Pump the tire up to max and then release the air that may clear any dirt out. If it's leaking around the base it needs patched or replaced.
Q:Is having a leaky valve normal?
Like most everything, there are degrees of valvular leakage. A valve can be leaking a lot or a very little amount. Valves are a biologic mechanism and therefore are not precisely manufactured with some areas that don't ideally fit, leading to minor leakage. If you were to take 100 random people off of the street and do an echocardiogram, the vast majority would have one valve or the other that had at least some trivial leakage. Therefore if the majority of people have the same thing and it is not a pathological process, it is essentially normal. Next, certain valves leaking are much more important that other valves. Moderate leakage of the tricuspid valve for instance is not a particularly important finding. But moderate leakage of the aortic valve is a very big deal that requires close medical attention. In sum, valves with trivial leakage do not require serial exams for follow up or any special measures like antibiotics before dental procedures. Since this is such a common finding, it is reasonable to consider this a normal finding. Not knowing precisely what the result was on your echo, I can not specifically advise you. At your next doctor's appointment make a note for yourself to ask him/her for clarification. Good luck.
Q:Does a valve have to be completely opened or closed?
you have water baseboard pipe heat running through your Wood burning Fireplace? is that correct? At the end there is a valve? If so these two have no correlation with one another. Your water heating system is pumped through with a circulating pump and the temperature is controled by a thermostat. If If the house is hot then you have a thermostat problem OR there are zone valves located within the piping that opens and closes according to your thermostat setting. If you are not getting comfortable temps then check this little zone valve motor and replace. Just open all the baseboards covers until you locate a little zone valve motor valve. Change this out and see what happens.
Q:How can I tell if my 2004 Ford Taurus a 12 or 24 valve?
I may be wrong but I think the 24 valve engines had a little badge on the body of the car that said 24 VALVE. Another thing that might help is look at the engine information on the white tag under the hood.
Q:Mitral Valve Prolapse and headache...any relation?
Although mitral valve prolapse is a lifelong disorder, many people with this condition never have symptoms. When diagnosed, people may be surprised to learn that they have a heart abnormality. When signs and symptoms do occur with mitral valve prolapse, it's typically because blood is leaking backward through the valve (regurgitation). Symptoms can vary widely from one person to another. They tend to be mild, develop gradually and may include: A racing or irregular heartbeat (arrhythmia) Dizziness, lightheadedness Difficulty breathing or shortness of breath, often when lying flat or during physical exertion Fatigue Chest pain that's not associated with a heart attack or coronary artery disease When your heart is working properly, the mitral valve closes during contraction of the left ventricle to prevent blood from flowing back into your heart's upper left chamber (left atrium). But in some people with MVP, the mitral valve malfunctions. In these people, the mitral valve leaflets are abnormal with extra tissue, bulging (prolapsing) like a parachute into their left atrium each time the heart contracts. The bulging may keep the valve from closing tightly. This may not cause problems if only a small amount of blood leaks back into the atrium. When blood leaks backwards through the valve, it's called mitral regurgitation (MR). MR can cause symptoms. Take care always! OIRAM
Q:Why use steel over brass in valve spindles?
Brass is used in some cases because it it less likely to corrode. It is used in other cases because it is softer than steel and can act as a bearing surface. Steel is usually used because of its strength relative to brass. In some cases they are used in combination so the steel surface and the brass surfaces compliment each other to provide a smooth sliding surface. Bronze is also a popular material for some valves and parts of other valves. Usually in water or steam service. Many times the valve seats are made from a harder material such as stellite. See site below for more info on stellite.
