Manual Operated Lug Butterfly Valve

Q: I don't have one single water shutoff valve in my house that will shut anything off completely. It looks fairly easy to repack them, and I have the tools, and there are instructions all over the internet. The question I have for the experienced among you is what packing material do I use? I have heard graphite thread and teflon tape and even joint compound.Is one better than the other? Easier to use?Also, if there are any pitfalls I should know about before I undertake this, please advise.Thanks in advance!: For stopping leeks use teflon tape to lub your valves use plumbers grease it s good idea to have a tube around not expencive

Q: i have a 05 kx250f, new valves recently,will pop start, idle runs high, has compresion, new kckstarter gear but it wont kickstart. someone said the valves need to be shimmed.anybody have any ideals? thanks.: Who okorder /

Q: What are a sing of a bad Idle control valve, will this cause bad mpg?: Generally, a bad ICV will either be stuck open from carbon or dirt making the idle stay too high. Or dead which usually kills the engine when put in gear. Mileage would be affected, but if it idles good, it's probably ok.

Q: The Hawker Tempest was the fastest piston powered airplane ever made, it had a sleeve valve engine. It was made obsolete, by the Me 262 and other jet engined fighters, But it's engine was the ultimate piston aircraft engine. Then piston engines became something for inexpensive planes, but why has the sleeve valve not undergone further development as a sports car engine?: i like to call them the two creation memories of Genesis the 1st tale which starts Genesis a million and ends Genesis 2:3 the 2d tale starts with Genesis 2:4 and keeps onward. on the tip of Genesis a million:27 it states that God created the two guy and lady which gave upward thrust to the perception that guy and lady have been created on an identical time interior an identical way wherein the guy replaced into Adam and since the story is going the female replaced into Lilith. yet of direction you will desire to comprehend that the Lilith tale is basically that a narrative in fact the Hebrews did no longer even supply her a acceptance the call originated latter on however the Lilith tale is folklore. The Lilith tale began for the period of the Babylonian exile of the Jews in spite of the undeniable fact that it would evolve for the period of the middle an prolonged time in Europe.

Q: if i put a power valve on my honda xlr 125 would it make my bike have faster acceleration: The powerband is caused by tuning an engine, they are most noticeable on a small lightweight 2-stroke. When you are riding and you change up too early you will have noticed the bike slows down and does not accelerate very well, but if you keep the rpms within a certain range it will accelerate smoothly – that is the effect of a powerband, it can be moved up or down the rev range by altering the ports and by changing the harmonics of the expansion chamber (the trumpet shape of the exhaust system). Either your garage is having a laugh at you or they are hopeless – I suspect the former. EDIT: You make it faster by tuning it –?making it less reliable and these bikes are already peaky. If you make them more peaky you will need to run them at higher revs –?higher revs = more power from available torque, therefore you do not want to move the powerband down the range or broaden it. Changing the sprockets will not improve acceleration AND top speed it is one or the other.

Q: Do blow off valves serve any purpose besides making the hiss when you shift? how much does one cost?: Blow off valve or dump valves are used on cars with large turbos. Their function is to keep the turbo spinning during gear changes or on the over-run. Because they are driven by the exhaust gas the turbo has a lag (delay), it takes time so spin up or slow down compared to the engine speed. The bigger the turbo in relation to the engine, the bigger the lag. By dumping the excess pressure it keeps the turbo spinning reducing the lag when you get back on the throttle. It will have no effect on power on small turbos so all these boy racers you see in civics have wasted their time and money. PS The noise it makes, I think is PTCHOO!

Q: ok so my 1993 bonneville started shaking and its smells like gas fumes in the car, so i cant drive it cause i have a newborn baby.so i took it to the dealership, they said codes 53,54,55,42,66 came up. they said i needed a new cadiletic converter, so i went to a local muffler shop. they said it was glowing cause it was so hot and said that wasnt the problem.i called the dealership back and they said they cleaned the egr vavle but said maybe it needs to be replaced, well before i spend any money i wanted to get everyones opinion, the car drive great, only shake when ur at idle. and smells awful inside uld this be the egr valve ?: A catalytic converter will glows red hot when raw fuel is introduced directly into it. The dealer is incorrect in saying that there is a problem with the converter itself. The problem is stemming from either the fuel or ignition system which would allow unburned fuel to pass through to the converter. Some possibilities are improper ignition timing, fouled spark plugs, air pump failure, Even though the catalytic converter glowing red hot is not caused from a clog if the converter is operated too long at a high temperature, its substrate will melt and re-harden. This would in turn cause exhaust blockage. Fix the fuel problem first and if the engine is still running rough (without a red hot converter), then it will need to be replaced.

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 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: If you suffer from Heart Valve Disease why do you get tired or struggle breathing?: There are four valves in the heart. (Bicupid valve and aortic valve in the left side and tricuspid valve and pulmonary valve in the right side). You have not stated which valve is affected. Valvular heart disease may cause shortness of breath (dyspnea) and heart palpitations. You may need surgery if your valve does not work properly. * A valve that does not close all the way will allow blood to leak backwards. This is called regurgitation. * A valve that does not open fully will restrict blood flow. This is called stenosis.

Q: Can someone please explain the difference between a pressure tap valve and a gate valve (if any).: Pressure tap valves are usually globe valves which have a disc with a rubber seal on it that turns down on a threaded shaft which as it turns closes off the flow of the water as it gets close to its seat bottom. Some pressure tap valves can also be ball valves which have a ball in them that has a hole in it. as the ball is turned the process fluid is controlled by how much of the hole in the ball is exposed to the line. A gate valve has a gate in it or I like to imagine it as a wall in a secret passage. As it is turned down the 'gate' slides down a grooved path to close off the process flow. like a secret door. They all are used to control the flow of a process. Which kind of valve used is determined by what kind of process you are controlling, the temperature and pressure are considered as well as what kind of control one needs.
