Manual Operated Lug Butterfly Valve

Q:I heard alot about blow off valves making your engine run rich, but I want to get a blow off valve or bypass valve when I get a wrx. (I know some people think they're gay) but i dont care how loud it is, just want that sound. so what's the difference? I've been looking at this one:: They guy above has some of it. The reason it runs rich is because when the stock by pass valve releases the air back into the intake, it does this after the MAF sensor. Since it is getting a big surge of extra air that the MAF does not read, the ECU automatically increases fuel for a split second when the BPV releases. When you suddenly release all that air into the atmosphere, the computer does not know it and still ups the fuel. That seems like not a big deal but it runs really hot and can do things like foul up plugs and even melt the catalytic converter. There is also the issue with most aftermarket units causing stalling when you first step on the gas or even when sitting still. If you want a little noise, I would first look to getting rid of the intake silencer in the fender. It looks like a milk jug. If that's not enough, then look into an open ended intake. Just be careful with intakes as they also can cause issues depending on the brand and they rear of the car. At least an intake ca be tuned for though. The issues with a BOV can be reduced a little with tuning but can not be eliminated. Sow know that you know the risks and how it does absolutely zero to benefit the car, spend the money on something better.

Q:My sump pump shut-off valve is very noisey. I wrapped insulation around it, but it still clunks. The clunk can keep me awake.: If you mean the discharge check valve, it will clunk when the level switch trips the pump. The head or weight of the water trying to flow back into the crock causes the check valve to slam closed, making a clunking sound. This is pretty common and normal.

Q:I took my 2nd valve out to wash it (i couldn't find my oil, but it worked fine) and I've tried making the number face the mouthpiece, yet it still is messed up and won't let me play a lot of notes.: see if there is a slight protrusion on the valve. probably on a piece of plastic near or above the spring of the valve? that should fit in a notch in the trumpet valve tube. Just insert your valve partly in until the protrusion is resting on a ledge-like part. Then turn your valve around the tube gently until you hear a click when the notch goes in. You are right, the number on the valve usually faces the side where the mouthpiece is. Make sure your other valves are also placed in there correctly. If all else fails, ask the person who's teaching or taught you to play trumpet. or go to a trumpet store. Enjoy practicing!

Q:My fiance needs his aortic valve replaced. He is 40 yrs old otherwise healthy. I am wondering how long he will be in surgery, how long he be in the hospital and any other info about having this surgery.: This is major heart surgery that is done on bypass (cardiopulmonary bypass, meaning the heart and lung machine. This is very serious. He may be in the hospital for a week or more. He may need cardiac rehab to gradually be able to do simple things.

Q:Steam is a gaming network and valve is a company, but what else? I think that it might be nothing; they both suck at working.: I don't understand this question fully, but I think you like my answer: Steam is a software for gaming articles, but it also meaning gas on another word. Valve (www.google.rs/search?q=Valvehl=srclient=firefox-ahs=SCurls=org.mozilla:en-US:officialprmd=imvnssource=lnmstbm=ischei=8zHfTr2iIsKnhAeTy-yVBQsa=Xoi=mode_linkct=modecd=2ved=0CCgQ_AUoAQbiw=800bih=393) is a legal company, same as meaning the link I put there. Hope it helps! :)

Q:I have my head off now I need to change my valves how do I do it?: The valves may not just slide right out. The keeper sometimes form a bit of a ridge on the valve.You need to remove that little ridge first if they don't just slide out. After they are out the guides may need work to achieve proper fit and centering of the valves. The valve seats may also need to be ground. Most of the time it is easiest to take the head to a machine shop for the valve work.

Q:My eight month old daughter was just diagnosed with pulmonary valve stenosis. Anyone have an experience with this? Did you have cardiac catherization? Did that fix the problem?: I had a different heart condition in high school. Mine was called superventricular tachicardia (SVT) but it required a cathedar in my heart. I had the ablasian surgery twice. We're not sure if it didnt work the first time or if there were two seperate problems, but after the second surgery I havent had any problems. Speak more to your doctor, he should be able to tell you more information and answer all of your questions. For me the surgery meant putting me to sleep and inserting the cathedar through three arteries, one on each side of my shoulders and one in the groin. I have very small scars that arent very noticable and I went home the next day.

Q:I'm thinking about getting a Cold air intake along with a Bypass Valve to prevent Water Indigestion on my Toyota Corolla 07. I was wondering if Bypass Valves actually work and can someone explain to me the physics around it???( How bypass valves work): Air Intake Valve

Q:i have got a problem with the valve but i have some guy gonna try and clean it next week. i have heard of blanking plates. has anyone used one of these? do they make any difference in the way the car goes ?: Ford Mondeo Egr Valve Problems

Q:One of the zone control valves in my heating system does not appear to be working. The thermostat is calling for heat, but no water is flowing. If the other thermostats call for heat, the valves seem to open as the pipes above the valve get hot from the water flowing through. The one that appears busted gets luke warm at best. All 4 valves in the system are fed from the same pipe, and the failed valve is the third in the series of 4 along the pipe (and #4 flows fine) so it doesn't appear to be something in the feeder pipe.Is there anything I can do to try and fix the existing valve, can I replace the valve myself? Would replacing the valve top of the valve (the green/gold portion) possible fix the issue (maybe a problem with the operation of the piston? Is there anything I ahve to do before removing the valve top aside from removing power to the valve?: if you have a circulating pump .shut it down [as well with the electric switch to the boiler] follow both pipes coming and going from the boiler shut any valves thus isolating the manifold slowly remove the zone valve .there will be a little water leaking out .replace valve amd hook up electric to valve .before u do all that take two jumpers and jump out the valve to another .see if u have a bad cir cut
