Q:how to check valve clearances?
Adam S, you're both right and wrong as far as needing to adjust valves. I changed 2 shims in 100,000 miles on my Kawasaki KZ1000, but my 1300 Kaw touring bike with nearly identical valve train needs checking and adjuuting every 6,000 miles or so. Go figure. Kneedragger, since your bike requires manual adjustment, you're valve train is either going to have a rockerarm type system with threaded screws and locknuts (easy) or use shims of various thicknesses to adjust the clearance (harder). Some have the shim on top of the 'bucket that covers the valve spring. With these, you will need a small, rather inexpensive tool specifically made for your model engine to compress the spring, allowing you to remove the shim. Other engines have the shim under the bucket, requiring you to remove the camshaft to change the shim. No special tools needed here, but reinstalling the camshafts correctly is absolutely vital. While this proceduere sounds rather intimidating, just remember that checking is all that may be necessary and no adjustments will need to be made. To check clearances, the idea is to turn the camshaft to that the cam lobe is pointing away from the valve and then measure the clearance with a feeler gauge and see how that compares to the recommended clearances. On shim type, clearances nearly always tighten and if the clearance is too little, you will need to install a thinner shim. I write down the clearance for each valve each time I check the clearances. If one valve tightens up faster than the others, this will give you a heads up to a possible future problem. Or, you may find they are ok this time but at the next check, you find some that need adjustment and will decide to take it to the shop that time. After a few checks and recording the clearances, you'll get a pretty good feel for how often you need to check them again. If you decide to do it yourself, by all means, get a shop manual.
Q:electronic valves from the '60s uses?
Valves (we call them 'tubes' here in the US, but 'valves' is actually a better description of how they work) were used on all kinds of electronics up to the 1970s. Radios and TVs mostly but also musical instrument amplifiers, PA system, etc.etc. In fact some high-end 'audiophiles' believe valves give you a better sound, so even today there are special (very expensive) amplifiers for both stereos and for guitars, that still use them. Only certain ones though, the ones that do final-stage amplification. And they still make the valves for these. People will want them for restoring old electronic gear, and to keep on the shelf in case one of theirs dies (they have a limited life). I have no idea what they're worth, but the answer to that question is: Whatever someone is willing to pay for them. So you have a few choices. Find shops that restore old electronics and call them and ask if they have anyone who would asses your valves, or even better, if they're interested in just buying the whole lot of them as a lot. Or go on EBay and look for the particular numbers and see what they've been selling for.
Q:marching baritone valve problem!?please i need help!?

Q:What opens the atrioventricular valves?
The opening and closing of the atrioventricular valves is controlled by the differences in pressure across them: When blood passes from an atrium to a ventricle, the atrioventricular valve is pushed open (and the papillary muscles relax and the chordae tendineae lose their tension, becoming slack). At the next stage in the sequence the ventricle contracts. This forces blood out from the ventricle into the artery via which it leaves the heart. This contraction of the ventricle and the corresponding increase in blood pressure within that ventricle also presses the cusps of the atrioventricular valve together until their edges meet, closing the valve. At the same time, the papillary muscles contract and the chordae tendineae tighten - both of which also help to prevent the cusps from enabling the atrioventricular valves to open. When in the next stage of the sequence the ventricle relaxes and the atrium contracts, the blood pressure situation is reversed, the relaxation/tension of the papillary muscles and the chordae tendineae also reverses, and the atrioventricular valve allows blood to pass from the atrium to the ventricle again.
Q:Will A Stop Valve Switch Off Water In The Bathroom Only 10 Pts?
Only water what is still in the pipes will come out but you will lose all your hot water in the hot water cistern if you have that type of hot water storage tank.
Q:i need help identifying a broken valve in a van?
The valve can be bent or broken under the head. Just because it looks right up top only means the stems are OK. The stems are usually OK, even if the valves are bent and broken. If it's making horrible valve noises and you're not sure, it's probably got a bent valve. Only way to know without pulling the head is to do a compression test.
Q:700r4 throttle valve......?
The only thing i can think you could have done i bent the peice that comes out of the trans. If the throttle valve still returns like a spring when you pull it with your fingers and you can still hook the tv cable to it it should be fine. unhook the tv cable at the carb or throttle body to hook it to the valve then hook it back to the carb or throttle body.

Q:Valves that control flow of substances througha alimentary canal?
The gastrointestinal tract is thus equipped at critical junctures with a number of muscular valves, or sphincters , which, usually under the direction of the autonomic nervous system, can regulate the movement of food through the digestive tube. Another function of a sphincter is to prevent backflow of partially digested food. The muscles of a sphincter are often described as “pursestring muscles” because the way they draw together the sides of the digestive tube is roughly similar to drawing up the strings of a purse. The first of these pursestring valves occurs at the cardia , the opening where the esophagus meets the stomach, and is called the cardiac sphincter , from its location almost directly in front of the heart. (But there is no physical connection.) Another important muscle ring is the pyloric sphincter , at the opening called the pylorus , located at the other end of the stomach, at the connection between stomach and small intestine. The release of waste from the rectum is controlled, partly voluntarily, by an anal sphincter , located at the anus , which marks the end of the tract.
