Q:Audi a4 S-Line need LOUD Blowoff valve?
The 2.0t uses a recirculation valve that's incorporated to the turbo. Don't get a typical blow off valve as this will not work for your car. It is also solenoid operated so it wont be what most tuners are used to when it comes to blow off valve. You will get some extra sounds when under part throttle but this is due to the way Audi designed their car. This helps eliminate turbo lag by already having some pressure in the intake track even when not needed. By venting this to the atmosphere (BOV instead of recirc valve), you may reduce the engines ability to produce boost from part throttle to full throttle. This will cause an increase in turbo lag. This isn't all that noticeable though. As far as the loudest, they're all gonna be about the same. There is only so much that can be done on an internally regulated recirc valve to make it a real blow off valve. Most are going to be a spacer plate that has holes in it to allow for pressure loss to the atmosphere when activated. There are some companies that have relocation kits that allow the use of a typical mechanical type blow off valve. ATP turbo has one for the A3 but I don't think they have one for the A4 yet. Do some research before you buy and if possible, try to get a sound byte on the net to see if its exactly what you're looking for.
Q:what type valves used mostly in pneumatic system?
It depends on what sort of system you are operating. Most butterfly valves leak, a few don't. Ball valves are instant operation, and don't normally leak. Needle valves are used for fine control of the flow rate. Gate valves are quick to operate, and don't normally leak. On aircraft pneumatic systems, butterfly valves are common, where a leak is permissable. Where no leak is permissable, slide valves are used, which have rubber seals.
Q:i'm being charged $300 to replace a 75gallon water heater valve, is that too much?
on the high side 60 bux other than that you can get half a new heater for 300$ crazyness/
Q:how to calibrate a pneumatic control valve?

Q:how can multi valve prolapse affect me? (13 year old female)?
Do you mean Mitral valve prolapse? The mitral valve helps blood on the left side of the heart flow in one direction. It closes to keep blood from moving backwards when the heart beats (contracts). Mitral valve prolapse is the term used when the valve does not close properly. It can be caused by many different things. Most people have no symptoms, but some people have chest pain, a rapid pulse, awareness of heartbeats, migraine headaches, fatigue, and dizziness. In a small number of cases, the prolapse can cause blood to leak backwards. This is called mitral regurgitation. Mitral valves that are structurally abnormal can raise the risk for bacterial infection. Some forms of mitral valve prolapse seem to be passed down through families (inherited). Mitral valve prolapse has been associated with other genetic disorders.
Q:Has anyone had surgery for Mitral Valve Prolapse?
My mom did in may 2005. She was able to have it repaired, and she is doing great. It was painful for a few weeks, but shes good now.
Q:Who knows anything about a leaking heart valve?
You have not stated which valve is leaking. Most probably Valve complaints are due to mitral valve and/or aortic valve. Heart valves are damaged due to rheumatic fever. Mitral stenosis (MS) is narrowing of the mitral orifice impeding blood flow from the left atrium to the left ventricle. The (almost) invariable cause is rheumatic fever. Common complications are pulmonary hypertension, atrial fibrillation, and thromboembolism. Symptoms are those of heart failure; signs include an opening snap and a diastolic murmur. Diagnosis is by physical examination and echocardiography. Prognosis is good. Medical treatment includes diuretics, β-blockers or rate-limiting Ca channel blockers, and anticoagulants; effective treatment for more severe disease consists of balloon valvotomy, surgical commissurotomy, or valve replacement. Mitral regurgitation (MR) is incompetency of the mitral valve causing flow from the left ventricle (LV) into the left atrium during systole. Common causes include mitral valve prolapse, ischemic papillary muscle dysfunction, rheumatic fever, and annular dilation secondary to LV systolic dysfunction and dilation. Complications include progressive heart failure, arrhythmias, and endocarditis. Symptoms and signs include palpitations, dyspnea, and a holosystolic apical murmur. Diagnosis is by physical examination and echocardiography. Prognosis depends on LV function and severity and duration of MR. Patients with mild, asymptomatic MR may be monitored, but progressive or symptomatic MR requires mitral valve repair or replacement.
Q:Should propane come out when valve is open?

Q:Function of reed valves?
Reed Valves
Q:Does mitral valve prolapse prohibit weight lifting?
overall picture doesn't prevent you from doing mild to moderate exercise, but with wait lifting we should think twice.
