Q:Anybody with a valve replacement?Which valves do u think are more successful,mechanical or natural?
Usually with an artificial valve, you'll need to be on a blood thinner for the rest of your life. If they use a natural valve, you usually won't need the blood thinner - perhaps you will for a little while, but not permanently. You can request a natural valve, but the surgeon doesn't know what size/shape of valve you need until he actually opens you up and sees what he's working with. He has an idea, based on the x-rays and MRIs you've had done, but he won't know for sure until he actually see it. So the surgeons are going to request that the Organ Procurement Department to thaw out two or three valves, depending on what they see in the tests. You can't just keep thawing out valaves, testing them, and then refreezing them if they aren't what you are looking for, so if they turn out to not be a good fit, he's going to turn to an artificial valve. So you could request a natural valve, but because of the shape of the gap that he needs to fill, you may have to have an artificial valve. Blood thinners scare people, and your friends will tell you horror stories about how their uncle's cousin's Nephew cut his arm and bled to death because he was on a blood thinner! That could happen, but it is very rare. What does happen is that you will have to go to your doctor once a month and have a blood test, and if your blood is too thin, you need to ease off on the blood thinning medication. Or if it is too thick, you need to take more. If you're blood is too thin, you'll bruise more easily - which might be embarrassing if the bruise can be seen. Blood thinners aren't as dangerous as they make them out to be, but they can be inconvenient!
Q:pulmonary valve stenosis in my eight month old daughter.?
I don't know if it's the same but my son had aortic stenosis when he was born. After many tests it just went away and no they did not have to do a catherization. Never caused him any problems either.
Q:Riding with a Schrader/Presta valve adapter?
Yes, just leave it on the valve while you ride. I tuck mine in my seat pack, but there's no reason you can't put it on the valve. The presta valve should be screwed shut like normal, then just put the adapter on over it. One of the best little gadgets to have if you ride in the country. Lots of people have portable or shop air compressors, but only *real* cyclists will have a pump or air chuck to fit a presta valve. If you inflate your tube with CO2, be sure to let it thaw out before you unscrew the adapter to close the presta valve. It's easy to lose air or tear the rubber at the base of the valve if you don't. I rode with a guy that used to just tuck his adapter and a patch kit in the leg of his shorts because he wanted to travel ultralight. I guess you could do that, too, but I'd worry about driving them into your flesh if you happen to crash and land on them.
Q:What would valve seat faulty will cause my h22a?
It's the doctrine of alternative and end result. You made unhealthy offerings and are actually paying the penalties. If you had constant the EGR valve proper whilst the investigate engine gentle got here on, you do not need had the tickets. Cost of an EGR valve is beautiful small. But you selected now not to try this. When the plate ran out, you knew it was once out, and made the alternative to hold riding. When you obtained the primary price ticket you might have stopped then, and constant the vehicle and obtained present so there could be no MORE tickets. Again you made a alternative now not to try this, and hold riding, and get extra tickets. How lengthy could it have taken for you, or your husband, to make a sensible mobilephone name to the courts and give an explanation for your clinical situation? The courts could have gladly given you an extension to your look. But once more you made a alternative to disregard it till there was once a warrant on your arrest. Even now you've gotten made a alternative to invite a number of strangers at the Internet as an alternative than name the courtroom approach or authorized help to discover your choices. So, welcome to the exclusive global of penalties. Good Luck.
Q:Whats a better Blow off valve for a pt cruiser?
The Mopar Performance blow off valve is really going to be your best bet if the two are roughly the same price. The reason I say that is because the Mopar unit is designed to fit onto that car, therefore it is engineered to release excess pressure at a safe level for that engine. The Greddy unit is also going to typically require modification to make it fit and function properly. Unfortunately, what they don't tell you about universal units is the reason they are universal is because they don't fit anything until you make them to fit, you just have enough material and hardware to get creative with it. If you are looking to extensively modify your engine, then it may benefit you to go with the universal unit and just wait until you have your piping cut exactly the way you want it, this may give you better location or clearance using the aftermarket unit, but otherwise like I said, I would go with the factory performance BOV. If you have any further questions about your cruiser, please feel free to email me, I have had a cruiser for a couple of years now and have also done lots of customizing to cruisers for friends.
Q:Is it possible to reduce pressure, using a valve?
One control valve can reduce pressure, as long as there is always a significant flow through it. The main reason for using more than one valve is usually to reduce or prevent cavitation caused by a large pressure change through a given valve. Ethanol has a pretty high vapor pressure, so cavitation might be a problem. Control valve manufacturers usually provide design guides for their valve trim choices (often in software form) that lead you through the choices and requirements. Each valve design has different limits. But, my seat of the pants feel is that you can do this with one valve. I have included an example. I am not specifically recommending this company. -- Regards, John Popelish
Q:car engine question (valves and cylinders)?
Yes v6 means 6 cylinders (pistons). Each pistons need to have gas come in and out and so the valves open and close to do exactly that (breath). There are at least 2 valves per piston - one (set) for exhaust and another for intake. Sometime to make it breath easier, there are 2 valves on each set. The 2.5L mean 2.5 liters (the measurement of the pistons) or basically the engine. The larger the displacement the more powerful (theoretically). Of course the larger the displacement the more fuel need to be injected. The exception is TURBO charged engines which stuff extra air (and extra fuel) so even a small engine take more fuel than equal non-turbo engie. The Evo uses much more than high tech engine to be that good. Besides being powerful, it uses the computer to divide the power to all 4 wheels in such a way to keep the car pulling even in a hard turn. === The TORQUE is the actual measure of engine power. The horse power is a translation of torque into something that people understand (horse - power). Good Luck...
Q:Trumpet problems! No noise, just air! Valves sticking!?
its your lips...lol you/I can make a trumpet sound off with just the mouthpiece alone.... try again
Q:silicone purge valve?
There are a number of things that will Toss out and ERG code on Fords (another reason I will never own another ford as long as I live) Double check all joints around the EGR valve and the tubes that connect too it. You may have a pin hole in one of the tubes or a loose coupler. If everything checks out there. Verify the vacuum line going to the EGR is not cracked, rotted, broken, or clogged. If it is replace the line. Next you need to check and make sure the valve is opening at the correct time. If the EGR is slow to open, becomes stuck half way or is opening to quickly, these will all toss out EGR codes. Then there is the possibility that the tubes for the EGR, or the EGR it's self may be clogged as well. In which case you need to remove them and clean them out. Hope this helps in your trouble shooting. Good luck.
Q:Replacing dirtbike valves?
you *can* just put the valves seals in and run it but it is NOT recommended. If you want the best seal which will = the most power, the valve seats need to be cut. If your not running a titanium intake you could get away with just lapping the valves with course and then fine lapping compound. I know a lot of people who just lap them in, but the most professional way with the best results is to cut the seats.
