Q: Can someone explain to me what lead and lag time are? Also, what are the three flow characteristics? Linear, equal percentage but what is the third. If I wanted to have a minimum stop at 25% on a non-linear valve such as a butterfly valve, how would I achieve this. Obviously you cannot just restrict the valve by 25% of its travel as it is not linear: 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: where is the bleed valve in a 97 taurus????thank you: On virtually every modern car radiator it is at the bottom of the radiator on the engine side.

Q: I was diagnosed with Mitral Valve prolapse...I'm 21, 5.5 tall and 130lbs, I had a healthy lifestyle...my doctor said that my case isn't really sever..but i'm taking medications to keep it this way...something i cannot ask my doctor about, would intercourse be harmful to me? and how should I deal with it??? is it okay for me to have children in the future? and could my MVP be cured without surgery??: You can lead a normal health life with MVP. What it is is the valve between the left atria and left ventricle doesn't close fully like it is suppost to and some blood seeps back into the atria when the blood is being pushed out of your heart. MVP is more common then you think. The doc even said to you that your case isn't really severe. MVP cannot be cured without surgery at this time. However you'll be fine. Just keep to your doctor visits as scheduled to keep tabs on it.

Q: I want to put a blow off valve in my car to make it sound cool lol but i dont have a turbo yet ... do i even need one?: A blow off valve is completely pointless without a turbocharger. Without a turbocharger, there is vacuum, not pressure in the air intake. There is no pressure to blow off therefore the valve will never operate. You would never get the sound that you are looking for. So the device would be completely pointless. It would not even look cool. When someone would see it, they would think. What idiot would put a turbocharger blow off valve on an engine without a turbocharger. So it would look stupid, not cool.

Q: Hi.. I was looking forward to install an electric supercharger for my 2 litre non turbo engine.This unit is driven by an electric motor instead of being mechanically driven.My question is if I can install a blow off valve in between the supercharger and the inlet manifold? Will it work?: Hey guy. First off, you shouldn't even bother putting in an electric supercharger. The reasons are the about of boost you are going to need to see any REAL advantages you will not get from an elec. I suggest do what I am doing and spending the money to get a GOOD valve job and get everything polished to match and you will actually gain H.P. I have seen 32 hp gains out of a 2.2 I4 F2 engine from a probe by just adding a cold air intake, going to a 2 inch exhaust w/ header and a good valve job. Incidently, I now run 142 hp instead of the original 110.

Q: 1. Why is there an exaust valve. Isnt it only a port. Where do the gases that go into the exaust valve go?2. How does air enter the intake valve. If you look at a push rod diagram, you cant see where the air is enteringCan someone explain to me the valve concept: You're not dumb for trying to learn. In a 4 stroke engine the air goes into the intake manifold and into the intake ports on the head. There it interacts with the valve, which when opened allows the air to be drawn into the cylinder. Then the engine goes through the power stroke and then the exhaust is forced out through the exhaust valve.

Q: Its stuck to an angle where the metal parts of the wheel block the air pump from letting it secure itself around the valve so i cant put air in, it all comes out the sides, i dont want to have to replace anything for i dont know much about bikes, but any solution to my problem? Thanks: Take the inside valve out of the tire stem and either straighten the valve where it's bent or buy a new valve.If your valve stem cap has the raised tool to remove the valve with you won't need to buy a valve stem tool.

Q: I have an 07 mazda 3, I-4 with 16 Valve. Anyone know what 16 valve means?: Engines make power by burning fuel, and this is limited by the amount of air or rather oxygen that can be drawn into each cylinder. Some engines have a single inlet valve and a single exhaust valve. This would be a 2 valve per cylinder engine. So your average 4 cylinder car would have 8 valves. Some cars are 16v or 16 valves! The reason for this is that 4 smaller valves have lots of advantages over a pair of bigger ones! The main one as far as we are concerned is that a 16valve engine or rather a 4 valve per cylinder engine flows more air and makes more power than a 2 valve per cylinder one can.

Q: Does the heater control valve anything to do with the A/C ?My heater control valve needs replacing, as it leaks when I put my truck's heat on. No heat, no leak. I have to periodically re-add Prestone every once in awhile after using the heat . I've checked the valve and it only leaks when I have my heat on, if I don't use my heat, I don't lose fluid. But now I'm wondering if I use my truck's A/C, does the heater control valve have anything to do with the radiator fluid, or just the freon? Thanks in advanceCar Mechanic in training: The heater control valve has nothing to do with the A/C.

Q: The water inlet valve on my Kenmore washer leaks. Is there an easy way to replace it? Last time it broke they charged me over $100 to fix it.: Do a Search Kenmore inlet valve. very cheap. or better yet go to Home Depot and pick one up if your warranty has run out. They will soak u for labor everytime when u can easily fix it yourself.
