Q:I am doing a big project on Valve and it's games. I am currently doing some research on the company and wanted to see if anyone had any interesting facts or information about Valve that may be useful when doing research, thank you. :): Valve Corporation Information

Q:Yesterday，my friend told me his ball valve in garden was broken. He want me to help he find a useful ball valve. I find some webs, but not he want. So I want somebody to help me find the useful ball valve. Thanks.: You can now easily order or buy ball valve from Kusha Steels. They highly produce A-1 quality products, Have personally ordered their products several times.

Q:I own a 2wheel drive 2003 Hyundai Santa Fe 4cly. The engine light was on the code P0401 came up which is the EGR valve. I had it changed out the engine light came back on after I had made it almost home. I took it to auto zone same code came up that made me take to the shop for repair in the 1st place. Ugh. Please help! What's the problem???: My vehicle is throwing a P0401 code. I was going to replace it, but instead I am going to clean it and replace it. I know the mechanic will want to replace it and charge me well over $100 (I'm seeing the part go for around $52-$55). THe car was recently serviced with the valve cover gasket replaced.

Q:I'm picking up euphonium (brass instrument) after a 5 year hiatus. Can I still use my old valve oil and slide grease (Trombotine)?: As the others have pointed out, no, it doesn't expire, but I never use old grease myself. You get lots of spit transfer from whatever you're lubing up to the grease/oil and the bacteria from said spit has just been.. sitting there. Growing. And possibly multiplying. Sorry. I'm a germaphobe. That's just yucky to me.

Q:my pcv valve tube is broken in half I replaced it with a rubber hose does it have to be whole: pcv valve does not hepl transmission inany way it stands for positive crackshaft ventilation pcv valve is for emissions only it does nothing for transmission should be replaced on most cars every 48000 km, i would'nt worry about a pcv valve..

Q:Why are pig hearts valves used as replacements for damaged heart valves in humans? Are there any complications and are they still used today?: They are called porcine valves... they are used very frequently because you don't have to be put on anticoagulation. But, the down side is... they only last about 15 yrs and then they have to be replaced. A pigs heart is pretty close to a human one.

Q:Could I get some possible remedies for Mitral Valve Prolapse pain? I currently am off beta blockers, and I need to cope with the mild, moderate to severe chest pain I experience. Female, average weight for my height, nonsmoker, maybe one alcoholic drink a week, exercise at least 3.5 hours a week. What do others with mitral valve prolapse do that helps?: Beta blockers are effective in reducing the chest pain related to the mitral valve prolapse syndrome and there are some other lifestyle modification that you can do to help improve your symptoms. It is important though that you be evaluated by your doctor (which I am sure you have) to determine if this chest pain is truly related to the mitral valve prolapse and not some other cause of chest pain. Other causes of chest pain include musculoskeletal, anxiety, heartburn, etc. The treatment for these other causes of chest pain would be different than that for MVP and this is why it is important to determine the exact cause. The lifestyle modification that has been found to be effective for MVP symptoms like chest pain includes aerobic exercise training, the avoidance of stimulants (caffeine), alcohol and undue fatigue, and a reduction in stress. Regular aerobic exercise in people with symptomatic MVP was associated with decreased anxiety, increase general well-being, and a decrease in the frequency of chest pain, fatigue, and dizziness. Magnesium supplementation to individuals who are deficient in Magnesium and have symptomatic MVP was also associated with improvement in symptoms. Magnesium levels can be tested on simple blood tests to determine if you are deficient.

Q:Okay so my boyfriend's father is getting a heart valve replacement....he's so nervous he cried last night when he heard it will be in 2 weeks....and he's usually one of those tough guys has anyone or know anyone who has had this type of surgery. They are leaning towards a animal (cow or pig) valve...because with mechanical you have to take blood thinners for the rest of your life...anyways if anyone knows information on this or knows the pro's and cons of the two diff. types of valves please give me info. Thanks: Hey, Firstly, to answer your question, I quote from the Society of Thoracic Surgeons: ...there is little if any difference between valves. The principle advantage of mechanical valves is their excellent durability. From a practical standpoint, they do not wear out. The principle disadvantage is that there is a tendency for blood to clot on all mechanical valves. Therefore patients with artificial valves must take anticoagulants or blood thinners for the rest of their life. bovine or porcine valves have ...a reduced risk of blood clots forming but all are less durable than mechanical valves. Given enough time, they will probably all wear out. The options in this category include xenograft valves made from animal tissues (most often pig aortic valves), homograft or allograft valves retrieved from human cadavers, and pulmonary autograft valves moved from the patient's pulmonary artery on the right side of the heart to the aortic position on the left. The decision on the type of valve used should be made in conjunction with your cardiothoracic surgeon and your cardiologist. Ultimately the choice will depend on a patient's preferences, lifestyle, and individual risks as determined by age and other medical conditions. The risk for this kind of surgery is really high and depending on the individual the outcomes may vary. What I think your boyfriend's father needs now is reassurance from you guys, it must be really hard for him to have to expose his vurnerable side since he's always been the tough guy around. And look online for informations: www.nlm.nih /medlineplus/tutorials/heartvalvereplacement/htm/index.htm Medline is one of the most reliable database, I'd say you can read up the surgery there.
