Q: My house has hot water baseboard heat. In the basement, there is a wood burning stove (now it is like a radiator) that has the pipe system going through it Between the pipe in and the pipe out is a valve. Does it have to be opened or closed all the way? There is no other way to control the heat in the basement I was thinking of opening the valve half way, but I do not want to destroy the valve.: There are basically 2 types of valves, gate valves and globe valves. Gate valves are designed to either be opened all the way or closed all the way. Globe valves are designed to be able to throttle flow proportionately. They can control flow from 0% too 100% or anywhere in between. Setting your valve to the halfway position will not harm it, regardless of what type it is. Experiment with it a bit to find the setting that works best for you. Be aware that if you reduce the flow of water through the heat exchanger portion of your wood stove, the heat will have less water to be absorbed into. That could result in the water overheating and turning to steam. That will cause pressure to build in the line or pipe. Too much pressure will burst the pipe and could be hazardous.

Q: I have a 97 Neon. The Canister Purge Valve circuit gives a code 31 stating that it has a problem. I've replaced the valve, which didn't make the code go away. I removed the battery for a few hours, and the code went away. I drove for about 2 weeks and the code came back on. If it's not the valve, where do I look next?: Could you describe this canister purge valve? Not sure what you are talking about here. Is it part of the emissions, part of the radiator, or what. I am just guessing it's part of the emissions. In which case, I need to know if it has a smog pump. Could be the pump, could be a clogged up cat, could be a bad EGR valve. Need some more info to help beyond this point. Good luck.

Q: Tryin to figure out how many valves a 1992 vx has. 16 or 8?: '92 Civics had single overhead cams (SOHC), so they have 8 valves. 1 intake valve and 1 exhaust valve per cylinder, so since there are 4 cylinders, that makes 8. Vehicles with dual overhead cams (DOHC) had 16, but Hondas had SOHC cams at that time. I'm really surprised how many people are saying 16. That is incorrect. I am positive. You cannot have 4 valves per cylinder (total of 16 valves) on a motor that has a single overhead cam.

Q: so here are the details. i've been using my trumpet for about 6-8 years now and 1 if not 2 valves get stuck on my trumpet. the problem is not the oil as i have over oiled them too and no go. its that when i try to put my valves back in their place and twist them they don't stay in place,move ,and making either my valves stuck or making my trumpet not do a sound. what should i do? repair shop or buy a new one? i hear the clicking sound when i put them back but still all that does is either make my valve more sticky: You really need valve oil I have used olive oil in a pinch

Q: used in pipe line: To allow adjustment for different pressures. The bellows extends under pressure. It works against the resistance of a spring to open the valve at the desired pressure.

Q: my friend needs a flap valve replacement. does anyone no how serious this is, i dnt wanna lose my best friend?!!!: Its heart surgery, which is riskier than many other surgeries, but valve replacement is routine procedure. There's a variety of different procedures that are used and several different types of replacement valves. Some valves can be repaired and some need to be replaced. Repairs usually give a person a normal or nearly normal valve that will last forever. Valve replacements don't work quite as wells as repairs and they usually need to be replaced in a decade or so. Most people can have the valved replaced by threading a scope through the arteries or using tiny incisions, but some people require open heart surgery. My friend had one of his valves replaced with a valve made from a pig heart and he was only in the hospital one night, and back to work a week later.

Q: she 13 and shes always sleeping what is a leaky valve there not telling me enough for me to understand and im a nurse tech im scared for her: I'm okorder /

Q: I have this air canister i want to attach to a homemade Airsoft gun. (please no comments or answers on that).The air canister has an opening on both ends. I thought for simplicity, put a filler valve on one end and a connection to the gun on the other.Exactly what kind of one way filer valve will i need, most of the ones i look at look like propane tank connections and those are for filling and dispensing into the system.: go to a tire store, get a tire valve, then you can fill it with any kind of air pump.

Q: I keep the tire pressure in my tires at approx 40 lbs per tire. I have an inexpensive tire gauge that I use to measure the pressure. Recently, one tire seemed low, so I measured the pressure and the batteries were dead in the tire gauge. I replaced them and measured again.It said 20.5! I thought I was going crazy, but then measured all the other tires and they were around 35 to 40. I filled up all the tires to about 40, but when I measured the weird one again, it said only 30!The question is, could there be a problem with the tire valve that is preventing me from getting a good measure of the pressure? I filled up the tire to where it looks really filled up, and I'm afraid to overfill it. I'd like to get it to 40 lbs but I don't know if it's already gt; 40 lbs with a tire valve problem. Or if a tire that's at 20 pounds can look so filled up that you couldn't tell it from a tire that's at 40 pounds?Any info would be appreciated.: Get rid of the battery powered one try the old mechanical pressure one. 40 psi sounds a bit much unless it's a truck. On the drivers door, there's a sticker which says what the pressure should be for that car w/ that size tire on it. I advise you follow the recommendation. The vehicle was designed w/ that tire in mind to get the best performance fuel economy. If the valave is bad, simply change it out. Go to a professional tire store before you do that. It could be more than you think.

Q: If you suffer from Heart Valve Disease why do you get tired or struggle breathing?: Heart valves are barriers, described as doors by the Texas Heart Institute (see Resources) that control how the blood flows through the heart, and ultimately throughout the body. When one of the four heart valves becomes diseased or damaged, you are at risk for more serious heart problems because your body must work too hard to get the blood flowing. There are several causes of heart valve disease that can be treated through medications and corrective surgery. Infection Heart valve disease can be caused by certain types of infection. Older people who had rheumatic fever before antibiotics were used to treat the disease may have sustained heart valve damage. Infection of the valves themselves and the walls of the heart can cause heart valve disease. Congenital Causes Some people have heart valve disease simply due to how they were born. Congenital defects of the heart include a mitral valve that is narrower than usual, or a misshapen aortic valve. Tissue Degeneration Older people may have valve dysfunction due to a degeneration of the tissue of the mitral valve. This condition is called myxomatous degeneration. Thickening A thickening of the valve itself, most often in the aortic and mitral valves, can lead to valve disease. This is another cause that is more commonly seen in the elderly. Heart Disease You can develop heart valve disease if you have had other types of heart problems, including coronary artery disease or a heart attack.
