Q: Im looking for a new BBb tuba. i would like six valves at 4+2. but if not looking for 6 valve BBb tuba: I don't know how long you've been playing tuba but 6 valve BBb tubas are virtually non-existent. No current brass instrument manufacturer will have that in their line-up. Tubas with 6 valves are already rare and are pretty much limited to F tubas. If you want a 6 valve BBb (I don't know why you even need/want that many valves) then your best option would be to buy a 5 valve BBb tuba and having it modified to include a 6th valve. Either way, expect to pay a minimum of $10000 (ten thousand) for the instrument.

Q: I am going to replace the EGR valve on my 99 Pontiac GP with the 3.8. It needs replacing(has already been cleaned twice) and keeps popping the code for it. Anyways..my question is: after its replaced what do I need to do to reset the codes or computer? Someone told me to unhook the battery for a hour and that will do it???? Is this true? Any help out there?? THANKS!!!!!!!!!!!!!!!!!!!!: a great type of the time its not the EGR Valve, this something else. Do you no what code or codes have been discovered ? i've got seen the O-ring lacking on the percentvalve alot and this journeys a EGR code, verify the percentValve for the O-jewelry or while the engines ruining open the oil cap and verify to verify if theres a great vacuum there. if so the O-ring is lacking.

Q: Hi,I have a 2002 Honda Accord with 115k miles which recently gave a ECL. The Honda dealer identified this a P1457 and says that the EVAP bypass solenoid valve needs to be replaced1) is this referring to this valve?: Hi so what do to expect here it is well past the 8 years life a car is meant to last and well over the 100k miles also a lifetime this car was meant to expire at. so yes from now on it becomes something of a money pit.

Q: The shutoff valve for the hot water under my bathroom sink has a very tiny leak. It is coming from where the turn knob meets the valve.So long as the valve is either all the way open or all the way closed, all I get is a single drop every couple seconds. But if it is anywhere in-between, it is a pretty steady drip.What's the simple/quick fix for this? Replacing the entire shutoff valve is probably not an option because it is an apartment complex.: Shut Off Valve Repair

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!!: Go to the FESTO website. they should have all the answers for you in the downloadable litriture.

Q: Are these valves are a kind of heart chambers pressure sensors?What is keeping them interlocked 2x2?: It's all mechanical. The valves are passive things kind of like a screen door. When you push on them from one side they open, when you push on them from the other they close. The valves are assisted by some fibers attached to the inside of the heart similar to the way a screen door is helped by a spring attached to the door frame. It's the flowing blood that pushes the valves open or closed as the heart pumps. The path that the blood follows in the heart as it beats happens to make it so that the valves close two at a time. This is because the heart is actually four separate pumps that work two at a time. There's no direct electrical connection to the SA node. The only way they're connected is that the SA node firing is what causes the heart to pump, causing the blood to force the valves open.

Q: Hi. im wondering what reed valves do and can they put on a 4-stroke engine or not???Thanks for your help.Dune.buggy5: reed valves are in a 2 stroke cylinder head they are exactly like they sound like in a clarinet.. when the piston rises they are closed due to the position the port is in the cylinder . when the piston is down stroking it creates a vacuum hence the reed valve opens and the piston starts to rise closes the reed valve.. 4 cycle engines have mechanicaly activated valves from a timing chain and a camshaft which controls when the valve opens so the answer is NO NO NO

Q: Describe a typical semilunar valve and tell how it works: Semilunar okorder /

Q: give some application of varible throttle valve?: A throttle valve allows continuous control of the rate at which some fluid moves from a region of relatively high pressure into a region of relatively low pressure. An example would be in an automobile engine, where the throttle controls the rate at which air (at or above atmospheric pressure) enters the engine's intake manifold (near vacuum when the throttle is closed.) The throttle in an automobile engine is mechanically linked to the gas pedal (in case you didn't know).

Q: how hard is it to clean the egr valve on my 2002 Chevy Malibu? if you can give step by step or possibly a website/YouTube video link. thanks: Cleaning it could make it worse then your experiencing now, but if you want to here's the steps. There are two bolts holding the EGR val;ve down. Remove them, and use a can of carb cleaner to clean the carbon out of the two ports that are in the valve. Reinstall with a new gasket and run the car. If the check engine light comes on replace it. I recently got a EGR valve (not recommended but they work) from a local wrecking yard for my folks '99 Venture 3.4 ltr motor, replaced the one on the van because it was throwing the EGR code and it worked fine. No more check engine light.
