Q:Control valves?
Hope this helps in some way... To start the 3 main flow characteristics of a control valve are Liner, Equal percentage and Quick opening (or fast opening). If you interested there are also other characteristics. As far as i am aware the lead time is the time in which a signal is sent to the valve and the lag time is the time in which the actuator moves and closes the valve. The pysical movement. As for your final question the only thing i can think of is to alter the actual size of the butterfly valve or put a reducer before it. Sorry if my information was of little use.
Q:How serious are multiple leaking heart valves?
Depends on how severe the leak is. If multiple valves have only trace leakage then no its not more worrisome then someone with Mild, moderate or severe leakage in one valve because trace leakage is a very small amount and almost everyone one has some. Now if someone had multiple valves that were moderate or severe yes that is more worrisome then some one with only 1 mild, moderate or severe valve leakage. If multiple valves have only mild leakage i think 1 valve with severe leakage is still more severe. I am NOT a doctor so this is just things that i am fairly sure about but not 100% sure of. Go to a cardiologist and ask him/her if you want a reliable accurate answer.
Q:PVC Ball Valve air rifle questions.?
hi there in canada , at any big truck tire repair place they have tire valves that are like bunker fittings, that is to say a valve that has a threaded bottom end with nuts and rubber washers, you would drill the appropriate size hole in the pipe and put the valve through and tighten the nuts up against the washers making an air tight seal, that should work for you if they have them in au, good luck
Q:Can water inlet valves for washers be repaired or rebuilt?
You probably can not find a rebuilt valve or get the parts to rebuild one. If needed, it will probably need to be completely replaced. There is a good chance you do not have a valve issue. Turn the water valve off and remove the cold water line at the back of the washer. Inside the hose or on the washer itself, there should be a metal screen in the line that somewhat filters the valve and protects it from getting clogged with sediment. Remove the screen and clean or replace it. If the screen wire is not at the washer end try the valve end of the cold water line. While your there you may want to clean the hot water side also. If you are unable to clean the screen, new ones are available for minimal money at hardware stores. Yes the screen wire is necessary, by removing the line additional sediment may very well go into the valve when you turn on the water and cause a valve problem if you don't have one now.
Q:Leak from Pressure release valve?
They build up mineral deposits on the valve seat sometimes that will cause them to leak.Try lifting the lever to open it completely then flip it closed. That will sometimes clean the seat and stop the leaking. It might take two or three tries. If that doesn't stop the leak then you'll need to replace the valve.
Q:Intake/Exaust valves? Im stupid?
The camshaft is turned by the crank shaft and is in time with it. the cam shaft either pushes the valves open and closed or pushes on lifters or pushrods that drive the rocker assemblies that move the valves. On a two cycle engine yes under most circumstances the exhaust valve is only a port. On a 4 cycle engine like on a vehicle it has exhaust and intake valves. When the piston is on the exhaust stroke the exhaust valve is pushed open, the piston comes up and pushes the exhaust gas out through the open valve, near the top of the piston stroke the intake valve begins to open as well and for a very brief moment both valves are open this is known as valve overlap. This allows incoming air to help expel the burnt exhaust gas. The exhaust gas goes out through the exhaust port through the exhaust piping and into the air. When an engine is running or cranking (pistons moving) it creates a natural vacuum which draws in air, when the intake valves open air is drawn into the combustion chamber pretty simple. Then the air is mixed with fuel vapor and when the piston comes up on the compression stroke the spark plug fires and the air fuel mix burns and drives the piston down. The valves allow the engine (AKA some call it an air pump) to work and pump air. Without them the pistons would do nothing absolutely nothing.
Q:How to replace PCV valve on 2001 F-150 Triton 5.4 V8? Also, where is it located?
It coming out of the valve cover(s) there maybe more than one. You can tell what it is by the way it bends at 90 degrees and to remove it just pull up on it it'll pop right out. If you shake it and it clicks. That's not your problem.
Q:Another EGR valve question?
You obviously had a parts store diagnosis so maybe you should ask the person that put the idea in your head that the EGR was a problem for the answer. Did you know that an EGR code can be caused by numerous other problems.
Q:mitral valve regurgitation In Toddlers?
my nephew had it and needed surgery.
Q:what is an oil pressure relief valve?
its in oil pump some engines have a oil filter relief valve in behind the oil filter that can cause this problem but not certain if your engine does but worth a check
