Q:Valve Replacement Surgery?! ?
Valve replacements actually have very low morality rates like 1-2%. There are always risk's with surgery though, such as blood clots or irregular heart rate. The recovery in the hospital is generally 5-7 days, and then it can take anywhere from 8 weeks to a year to feel recovered.
Q:Can I take a reversing valve from a heat pump.?
something you would possibly want to do is tap the valve without making a dent. that's accessible it basically were given stuck. once you've a volt/ohm meter be sure that's getting skill. If it isn't basically save on with the strains decrease back till you discover the position the skill stops contained in the electric powered strains. it would want to also be a foul solenoid on the valve. in case you get better information, submit it. solid success.
Q:What is another name for a valve?
Valve comes from latin valva. There is not other name for it in engineering, but some times is referred as a cock, if the valve is used as shutoff valve, it is also known as shutoff cock. For irrigation, sometimes large gate valves are also known as gates. I can give you many names for the type of valves but I can't think of any other name that replaces valve.
Q:Can someone explain mitro valve prolapse vs mitro valve regeritation?
MItral vale prolapse is the problem that is causing the regurgitation. Regurgitation is backward flow of blood. Prolapse is a situation where an anatomical part has slipped out of its normal position. When a heart valve is prolapsed it doesn't close completely, and blood leaks backwards when the heart beats.
Q:transmission valve body?
Chevrolet did have a bad problem with valve body wearing out the bore where the valve rides. I would recommend you replace the valve body too, unless it has high milage and the transmission has never been overhauled. Then I would say sell it now! They also have a problem with the reaction shell breaking or stripping and causing a no reverse problem. Those usually go out around 150,000 to 170,000 miles. So if your in that range, and you haven't had it rebuilt or you don't want to spend the money to rebuild it. I would recommend you selling it now.
Q:Which is the intake and which is the exhaust valve?
the intake valve is usually bigger and on the left. the exhaust valve is usually smaller and on the right. at least it is true in small engines (lawnmowers).
Q:how man cups does the miteral valve have.....?
Mitral valve has two cusps. It is located between the left atrium and the left ventricle , oxygenated blood comes from the lungs by pulmonary veins and drains into the left atrium then the left atrium pumps this oxygenated blood through the mitral valve into the left ventricle. After that the left ventricle contracts pumping the blood through the aortic valve to the aorta..
Q:Help With My EGR Valve?
EGR valves are replaced much more often than they need to be. Most of the time the problem is not in the valve itself but in the EGR passages. The actual trouble code would verify that (I am expecting a P0401: Insufficient EGR Flow). The most effective approach is to remove the EGR valve, examine it for really bad deposits, then clean it with carburetor cleaner or replace it depending on whether it looks like it can be cleaned. In any case, clean out all the exhaust side passages. The second source has the usual vague ehow instructions while the third source has a more detailed but vertiginous video. EGR valves are pricey enough (typically $150) to make it worth cleaning before replacing. I personally have never had to replace an EGR valve.
Q:will correcting of mild dextroscoliosis will affect existing mitral valve prolapse?
