Q:Applicational uses of Reduced port & Full port ball valve?
W.W. Grainger out of Chicago ships all over the world, also McMaster-Carr Supply.
Q:valve oil mass order?
I wouldn't bother with that. I would go to Woodwind/Brasswind, and get their brand of valve oil. Very economically sound, and a very good product. Why go to all the trouble of getting bulk stuff and trying to put it into those little bottles. Get the company brand stuff. It works wonderfully and is half the price. Sometimes you pay for the names al cass, or holton, when all you are getting is just oil.
Q:Bicuspid Aortic Valve...?
VSD or ventricular septal defect is a congenital disease caused by failure of your ventricular septum to fuse with the bulbar ridges of your atrial septum during embryogenesis. Some VSD are fine since only a small amount of blood is shunted from LV to RV but a majority is still shunted straight to the aorta. An aortic valve stenosis which I think is what you are referring to is usually an adult disease associated with rheumatic fever, mechanical breakdown from hypertension, or death from an MI. Aortic valve stenosis is a bit more worrisome since this can lower the output of your heart by acting as an obstruction, which overtime can cause ventricular hypertrophy, a disease with whole set of other problems. New trends in VSD repair uses minimally-invasive surgery using a transcatheter that is inserted esophageally or through femoral artery; very small scars and short recovery time. Aortic valve repair may also be done this way in the future, but if your aortic valve is still patent, there is no need to replace it at this moment because it would require a donor and open heart surgery.
Q:check engine light- valve cover gasket?
I assume you checked the oil level. You can go to Auto Zone and have engine codes checked for free to see if you have a problem. I can't see how a leaky valve cover would cause the check engine light to come on unless it fouled some sensor but then again I'm no mechanic.
Q:can EGR valve make engine run hot, melt pistons?
Yes. An EGR valve reintroduces exhaust gas to cool the combustion chamber, making it run cooler, due to less oxygen. Oxygen burns hotter than fuel. So if you have a faulty egr valve, emissions will go up, and you run the risk of overheating and damaging the engine. It could cause the pistons to expand, or seize, due to higher temperatures. It was not as much of an issue in yesterdays cars, because they had much lower compression. Now tolerances are tighter, but metallurgy is also much better. It still does run the risk of running hot, and causing predetonation, which would destroy pistons and other engine components such as the crankshaft, and valves.
Q:Whats wrong with my trumpets third valve slide!?
instead of the standard cheapo trumpet grease, try a more generic brass instrument oil. also make sure you aren't tightening the valve screw cap too tightly. it's not a good idea just keep tapping it. also, unwanted moisture can create a seal that will sometimes inhibit the valve from popping back up. get it dried out as much as you can. also, don't use too much of anything - the oil, the grease, etc - excess will keep it from popping out too.
Q:would EGR Valve Temperature Sensor make a car run lean?
A faulty EGR sensor or the EGR valve itself would definitely make the car run lean at idle. The sensor regulates the amount of EGR opening at various coolant temperatures and manifold vacuum if it's vacuum actuated. If the diaphragm under the EGR valve has ruptured you'd get a straight vacuum leak plus lean condition if vacuum actuated. There's a simple test for EGR valves. Place a length of tubing on the valve port and dray vacuum with your mouth. Reach under the valve till you feel the rubber diaphragm. If the valve opens you'll feel it with your fingers. If it doesn't move the diaphragm has a hole in it.
Q:Rotary valve VS axial flow? (Trombone question)?
First, you should know that a valve trombone is different from what you're talking about. Valve trombones have three or four valves, much like a baritone or euphonium. What you're thinking of is called a symphonic tenor trombone, tenor-bass trombone (less common), or a tenor trombone with an f-attachment. The difference between the axial flow and traditional rotary valve on the trombone is one of feel. The axial valve is designed to provide less of a change in resistance between playing the horn with and and without the valve pressed down. Some people prefer that resistance. Either way, the quality of the entire horn is going to be a better indicator than the valve section by itself. Your best bet is to go to a local music store and ask to try out all the professional models - pick which one feels and sounds the best to your style of playing.
Q:97 explorer valve body solenoid question?
What are you? 9 years?
Q:Presta valve bike tube?
First off, there is no question that presta valves are better! The larger a hole drilled through a rim, the lower its strength. Thus, all other things being equal, a rim drilled for a presta valve will be stronger than a rim drilled for a schrader valve. Tubes with presta valves are slightly easier to pump with a mini-pump than a schrader valve. Finally, they are a bit lighter than a Schrader valve. Secondly, you need to buy a new tube. There is utterly no hope for a repair if the valve comes out. Hope this helps.
