Q:Sewer ejector check valve placement?
the check valve would be installed just outside of the crock vertically. The noise I doubt is from the check valve itself. I'd guess it is the pump shutting off and the pipe isn't fastened securely, so it bangs. Check to make sure that the run of pipe leaving the crock is fastened securely. if this is the case the only other option I oculd think of would be to re-position the check valve on a horizontal run of pipe as close to the crock as possible. Most check valves I have seen for ejectors are compression type, it will be messy but not to complicated. Keep a bucket handy, when you crack open that check valve you may need it. Flush the toilet until the pump kicks on a few times, this should clear out most of the nasty stuff. You may also need a short piece of 2 pipe and some couplings to make up for the space of the check valve. If you can hear the water flowing out when the pump kicks on and don't hear it draining back into the crock when it shuts off, the check valve is probably still good.
Q:what is the definition of differential pressure for valves?

Q:any way to treat aortic stenosis besides valve replacement surgery?
Every case and every patient is different. You could opt for a valvuloplasty or management with medications.
Q:Calculation of Shutdown Valve Instrument Air Supply?
Shut down valves I've worked with haven't had an 'Air Flow' for their operation. For the smaller valves, they consist of diaphragm operated valves either held open or closed by pneumatic pressure. The air supply at 25psi to give a diaphragm holding pressure of 15 psi, is via a solenoid valve which dumps the air pressure to either open or close the valve depending upon its function. (That of isolating a system or relieving pressure). The solenoid is actuated by a signal from the shut-down system, and the valve is a 3-way unit which isolates the supply air and vents the pressure off the diaphragm. Other SDV's in my experience, are operated in a similar way but are much larger and are operated by a pneumatic air cylinder and piston with air supplied at 100 psi. Others encountered are ... MOV's...Motor Operated Valves that can be automatically operated from the shutdown system, or Operated Remotely from a safe distance (ROV's).
Q:about a blow off valve?
I doubt the cops would notice and if they do find out which is highly unlikely to happen you would just get a fix it ticket. i live in cali and i hear cars with blow off values all the time so my advice is don't trip and put it on your car. it will sound so bad ***!
Q:Rotary valve VS axial flow? (Trombone question)?
First, you should know that a valve trombone is different from what you're talking about. Valve trombones have three or four valves, much like a baritone or euphonium. What you're thinking of is called a symphonic tenor trombone, tenor-bass trombone (less common), or a tenor trombone with an f-attachment. The difference between the axial flow and traditional rotary valve on the trombone is one of feel. The axial valve is designed to provide less of a change in resistance between playing the horn with and and without the valve pressed down. Some people prefer that resistance. Either way, the quality of the entire horn is going to be a better indicator than the valve section by itself. Your best bet is to go to a local music store and ask to try out all the professional models - pick which one feels and sounds the best to your style of playing.
Q:What rhymes with valve?
Sorry to all those saying salve and halve (and one could add calve) -- in these words the L is silent! Thus for valve there is no PERFECT rhyme (defined as using exactly the same sounds from the vowel of the accented syllable to the end of the word). The best you can do is a NEAR rhyme in which most of the sounds match, with as few sounds changed as possible, and the 'substitutes' matching as closely as possible. These COULD include dropping the L altogether, but I'm not so sure that salve, etc. work very well Varying the vowel: delve, elve [from a scientific acronym], helve (handle of a tool such as an ax), shelve, swelve ('to swallow'), twelve revolve, solve Varying the final consonant (and possibly the vowel) The closest match would be changing /v/ to /f/, but these words, again, mostly have a silent L (half, calf, ). The only exception? The name Ralph also changing the vowel: elf, shelf (but the -v forms are better matches) a voiced /th/ (as in this NOT thin) is fairly close to the /v/ sound -- as a result mouth (the verb form) might work. (why does mouth work better than salve? Perhaps because the ow sound is closer to the al of valve than to the short-a of salve, cat, etc.) health and wealth --with a changed vowel and un-voiced /th/ is little tougher, but maybe. . .
Q:Are OHC valves generally smaller than pushrod valves?
Depends on the displacement of the engine and the size of the valves use, generally speaking four valves will cover more surface area than two valves. Using larger valves is generally cheap than using multiple smaller valves and less mechanically complex as well. But larger valves often need to be stronger and stiffer valve springs are needed, stiffer/larger valve springs = more energy required to open the valves which means there's a loss of power there, you can get around this somewhat by using stronger yet light materials like titanium, but if you do that, it can get expensive. And there's also the option of using multi-valve heads on pushrod engines like you see in the diesels used by the big three. To answer your question, there's no hard and fast rule about it.

Q:Trumpet valves keep sticking!?
have you tried washing it out? ive played instruments i was going to suggest valve oil first but if that didnt work theres a good chance it needs cleaned inside and out and then oiled.
