Q:Pressure balancing valve adjustment in shower?
the new single handle tub and shower valves all come with a scald guard mechanism.(its code so kids cant turn on the hot and burn themselves). take the handle off and mess with it. it will be grey or black with a bunch of grooves on the outside. keep adjusting it till it satisfies you.
Q:What is motor operated valve (MOV) please answer me if anybody have experiance in instrumentation filed?
Motor Operated Valve
Q:an people with bicuspid aortic valve live long?
The mitral valve between the left atrium and left ventricle only has two cusps and it works fine. Since the valve going into the left ventricle has two valves, it stands to reason that a similar valve going out of the left ventricle would function similarly if it was the same size and shape. The number of cusps is not entirely related to how well the valve functions. In your case, the opening of the aortic valve is slightly smaller than normal, but clearly capable of passing an adequate amount of blood. The stenosis alone may be the only problem caused by the valve. The stenosis you have likely creates some back pressure when the left ventricle contracts. The heart compensates partly for the back pressure but this prolonged compensation wears on the heart valve a little more than normal. So, you end up with a heart that more or less functions normally but the back pressure and compensation cause the heart valve to wear out faster than normal. Its a gradual effect. The type of damage done from this circumstance is not something that changes rapidly. Evaluating the condition every three years is still probably a very cautious approach and its not certain that the stenosis will ever become a significant problem even if you live well beyond 70 years.
Q:Plastic ball valve help!?
=== take it back and get another valve .... if it doesn't work freely in your hand then the valve will be a problem if you install it ---- working with pvc you should use the purple glue that is waterproof and it is a good seal and no leaks when you have
Q:A quick question on Idle control valve?
Generally, a bad ICV will either be stuck open from carbon or dirt making the idle stay too high. Or dead which usually kills the engine when put in gear. Mileage would be affected, but if it idles good, it's probably ok.
Q:Mitral Valve Prolapse and headache...any relation?
Although mitral valve prolapse is a lifelong disorder, many people with this condition never have symptoms. When diagnosed, people may be surprised to learn that they have a heart abnormality. When signs and symptoms do occur with mitral valve prolapse, it's typically because blood is leaking backward through the valve (regurgitation). Symptoms can vary widely from one person to another. They tend to be mild, develop gradually and may include: A racing or irregular heartbeat (arrhythmia) Dizziness, lightheadedness Difficulty breathing or shortness of breath, often when lying flat or during physical exertion Fatigue Chest pain that's not associated with a heart attack or coronary artery disease When your heart is working properly, the mitral valve closes during contraction of the left ventricle to prevent blood from flowing back into your heart's upper left chamber (left atrium). But in some people with MVP, the mitral valve malfunctions. In these people, the mitral valve leaflets are abnormal with extra tissue, bulging (prolapsing) like a parachute into their left atrium each time the heart contracts. The bulging may keep the valve from closing tightly. This may not cause problems if only a small amount of blood leaks back into the atrium. When blood leaks backwards through the valve, it's called mitral regurgitation (MR). MR can cause symptoms. Take care always! OIRAM
Q:Where can I order foot valves?
Yes, okorder.com
Q:effects of a bypass valve on a car?
bypass valves are for cars with forced induction IEturbocharger,supercharger it allows the air that would normally be expelled into the atmosphere blow off valve and instead putting it back into the intake which helps with less lag in building boost again. If your car is not turboed or supercharged then forget it.
Q:EGR Valve drivability issues?
You really need to find a competent mechanic. (sometimes easier said than done). I have worked on cars for over 20 years and have NEVER seen a vacuum leak cause this kind of erratic behavior. If the codes will not reset, either the mech. doesn't know what he's doing or you have major computer problems. It may need to be replaced. The computers in vehicles are very reliable but not perfect. From what information you have given it seems that is the case. Before you go that route there are several sensors on this motor that could cause this. crank position, throttle position, mass air flow, etc. EGR would not cause this either. It have also seen coils breaking down cause this. This will get worse the longer the motor runs. (heat makes it worse). If you are not one to work on your own car I would start going to some differnt shops. Some times small shops seem to know more about troubleshooting than the dealerships.
Q:home water heater has 175psi pressure relief valve installed.?
Have you tried opening the valve for a couple seconds? Sometimes that will clean out the crud causing the valve to leak.
