Q:List words that rhyme with valve...I need these.

Q:is a 4 cylinder 16 valve.... 5 stars for the best answer....

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
Q:My valve covers are leaking how do I take the intake off my v6 firebird?
type into search box how to remove valve covers how to remove valve covers 1995 firebird pretty easy really just like ten bolts not tight and just have to remove what ever is in way of getting them off many times not much to it really only tip is to say clean old gasket off good and do not over tighten when repalcing they just hand tight really
Q:Is a leaky heart valve considered to be a form heart disease?
Hello, Yes, it is. Obviously the leak is still within the arteries, - no blood is leaking out of the heart, - any leak is only in the backwards direction of blood-flow. One function of the valves is to stop blood which has just been pumped, from falling backwards again to where it came from. As soon as the pumping action stops, the valve has to close to lock the pumped-blood in its new forward position. If any blood leaks back through the closed valve, that is called regurgitation of blood, - and the closed valve which is leaking is described as incompetent or insufficient, in medical language. Sometimes newborn babies are born with a heart valve (or valves) that leak backwards, having not been properly formed in the womb, - or sometimes the valve (or valves) are damaged in adult life by some disease, - for example, infections like Rheumatic Fever or Syphilis, (both rare nowadays). I hope this is of some help. Best wishes, Belliger retired uk gp
Q:and that i need a valve job. what is a valve job, and is it expensive? i have a stock 1.6 SI motor in it, but i want to make my car better and faster, would it be cheaper to buy a new engine? some of the people who want to buy my car say that they would put a B16 vtec in it. what is that, and how much better is it than my engine?
A valve job involves removing the head from the engine, disassembling the head regrinding the valves seats and installing new valve seals guides. new engine vs. valve job? Depends on how many miles are on the original engine. It's seldom a good idea to do only a valve job on a hi mileage engine. Valve job would be cheaper at first, unless you plan on keeping the car for a long time, then a new engine would be a good choice. Maybe the guy was just setting you up to ask for a lower price?
Q:This valve has flow indication embossed on their body.
Gate valves are used primarily for isolation, usually not for flow modulation. They are usually operated fully open or fully closed. Installing the valve with the arrow pointing in the direction of flow will have more to do with the tight sealing of the closed valve than with the operation when open. If the valve is to be installed in a pipeline where the flow is in either direction, pick the direction most important for good sealing. However, I do not recall seeing a flow arrow on a conventional gate valve.
Q:I would like to know about the signal pneumatic valves are drivesn (PWM,PCM?) and about their bandwidth and bit rate. Where can i find info?Thanx!!
first of all, lemme be frank to say that your question is not clear to me. however, i wud like to give my answer below with my understanding of your question. generally, the term pneumatic valve means that the actuating force to operate the valve itself is pneumatic(driven by air pressure) and not the service fluid (i.e. the fluid which passes through the valve). with the above understanding, industrial standard pneumatic pressure could be 3 - 15 psi (or) 0.2 to 1 kg/cm2. on the other hand, if your question means that you want to know about the electrical driven valves, then the industrial standard is 115VAC Solenoid valves (or) 24VDC Solenoid Valves. There could be other ratings as well.
Q:ok...i want to find a valve that controls air pressure so i can let it out in 2 different ways for my pneumatic potato gunwhat websites or stores sell this (not home depot)
You might have to register on the site to order online. It is free. You can call them and order the catalog. It is free also. Hope this helps Email me if you want me to look it up in my catalog. Don't break any windows. Wingman
Q:I got a new gas stove, but I can't find a shut off valve to take the old one out and put the new one in. There isnt one behind the stove on the line, and i went under the house and followed the gasline and didnt find one down there either. Can any one give me ideas where else to look?
Do you have a meter some where outside of the house? The shut off valve is usually real close to that. It is the type that you have to take a wrench to turn it off. I'm not trying to insult you I'm just trying to help. There will be a narrow bar on it and it will be pointing parallel to the pipe at that point. You will have to use a crescent wrench and turn it 1/4 turn until it is cross ways to the pipe. Good Luck
