Q:What great blood vessels of the heart have semilunar valves?
The semilunar valves are located between the aorta and the left ventricle and between the pulmonary artery and the right ventricle.(aortic valve and pulmonary valve) The semilunar valves are flaps of endocardium and connective tissue reinforced by fibers which prevent the valves from turning inside out. They are shaped like a half moon, hence the name semilunar (semi-, -lunar). they prevent the back flow of blood to left and right ventricles respectively.

Q:Any way to fix a leaky CPVC valve?
Turn off the main water to your house. Turn that valve to open. Then tighen the nut on it (slightly), see if the valve will close , if yes; then tighten it a little more, then see if the valve will close. If yes - that should do it. If the nut is so tight that the valve will not close, then loosen the nut just a tad. That should do it, ......... now, turn the valve off. Turn back on the main water to your house -- and see if that works.
Q:How does a thermal bypass valve work?
Many block valves in steam systems have much smaller bypass valves designed to make it easier to control the heating of cold steam lines during startup. Some control valves have by pass valves to permit work on the control valve without interrupting service. The heat exchangers have by pass valves so they can be taken out of service if they are not needed or for repair and maintenance.
Q:Does the number of valves make a difference?
Audi now uses 5 valves per cylinder. Why? They obviously believe it offers advantages over conventional 12 or 24 valve systems (for 6 cylinders) but it's not clear what benefits it has to Audi buyers. Is is just more complex and more likely to have problems? Who knows?
