Q:trucuspid valve... pulmonary valve??
Hello Inga, I'll help you this way. Form Follows Function. Remember that as you learn anatomy. It will guide you, make sense out of confusing things. In this instance, those two valves are not the same. They have very different requirements. Understanding the structural functioning of the heart will make this clear to you. Go back to the text, reread this section. Ask yourself. What are the differences between these compartments? Once you've an understanding of the cardiac cycle. You'll see ( hence remember it) for yourself.
Q:how can I buy a useful ball valve??
Hi here in the united kingdom the only place you would find a ball valve is in a tank like a header tank in the loft or in a toilet. then it would be a low pressure one or a high pressure one. what you have described sounds more like a stopcock which is a tap to switch off the main water supply to the property. which you should consult the water company about as it maybe there responsibility. so i would consult with them first.
Q:PCV valve = oil burning?

Q:what is a power valve?
A power valve is a device that manufacturers fit to the cylinders of highly-tuned 2-stroke motors. It's purpose is to vary the timing of the exhaust by changing the height of the exhaust port(s). This is done in order to allow these motors to retain some bottom and midrange power. A Honda xlr is a 4-stroke so you cannot fit a power valve to it. The exhaust port in a 4-stroke is in the cyliner head, not the cylinder wall, and it's timing is controlled by a cam acting on a poppet valve.
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:PCV valve location on 1987 chevy blazer?

Q:Can i smoke pot with and artificial valve?
Are you crazy, do you want to move in early at a cemetery? The reason for that bad valve could be your frequent encounter smoking ganja. Ganja has numerous amounts of varied chemicals, and the soot your bronchioles clogged with can cause less oxygenated blood to be dispensed by the heart thus plaques have form and a valve was damaged. It was all about the ganja smoking you did, then YOU WANT TO GO BACK AND COMPLETELY KILL YOURSELF AFTER A GRUELLING SURGERY WHERE DOCTORS GAVE YOU A NEW VALVE. BROTHER YOU DO NOT LOVE YOURSELF, AND SHOULD NOT COME ON YAHOO ANSWER FOR OPINIONS. SO IF YOU GOT SOMEONE SAYS YES, YOU WOULD SMOKE MORE POT. PERHAPS YOU SHOULD SEE A PSYCHIATRIST AND NOT A CARDIOLOGIST, AS YOU ARE ASKING A STUPID QUESTION.
