Q:Are they referring to the nozzle orifice or are they talking about the diameter of the nozzle? Does it mean the inner diameter of the valve like in a globe valve?: A 12 inch valve means it is designed to fit with nominal 12 inch pipe. Most 12 valves are flanged so these valves would also be flanged to match as 12 piping flange. They would also be sized to match the appropriate flange rating as in 125#, 250#, 150#, 300# 600# and so on. As to the opening of the valve that will vary depending on the type of valve. For a gate valve it will be very close to 12 inch in diameter. For a globe valve it may be a bit smaller. In some cases you will see what it called a reduced port valve where in internal opening is smaller. This is more common with large ball valve where the smaller ball and opening makes the opening/closing torque less. These valves also tend to have a venturi shape on the inlet and out leading to be ball so the pressure drop is closer to a full opening valve.

Q:I have been diagnosed with a bicuspid aortic valve and a discrete stenosis under the valve at 11 years old. I am now 25. My cardiologist told me I might need a valve replacement a 70. Can people actually live long with that condition? I don't understand it. And he only wants me to have an ultrasound every 3 years because nothing has changed in the past 10 years. Can my condition change in a short time? At a dangerous level? I have bad anxiety because of this.: 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:I have a 03 civic ex with 96k how important is it that I do a valve adjustment. The engine runs smooth.: the factory maintenance manual calls for the valves to be checked and adjusted if necessary every 110,000. unless they're noisy (loud tapping) they probably don't require adjustment. The older Civics were very sensitive to the valve adjustment but the 2003 won't give you any problems if the valves aren't noisy. that being said, if you notice a decrease in performance or fuel economy around that mileage it won't hurt to get them checked and adjusted. hope that helps

Q:First off I'm a girl. :) My 2.0 non turbo engine has a bent valve. I have been asked to pick up the valve. But I need to know if its for the intake or the exhaust. I know the guy how is going to fix it said he will have to sand down the cylender that it goes in it. The car sounds like it knocking when driving or sitting still. The guy who is going to fix it is at work right now and I'm suppose to order this part right now. Is it an intake or an exhaust valve?: tell him that you dont sand down the seat.if he does,then he could get it so it wont seat right.he needs to lap the seat.now 1 of the valves are smaller then the other.if it backfires through the exhaust then its the exhaust valve.if he know how to do it,then all he has to do is take a piece of paper and hold it up to the tailpipe and see if it sucks the paper in.

Q:My new Trek 1000 has a type of valve stem different from the standard (car type) stem on my mountain bike. Do I need an adaptor to fit it to a pump or do I need a whole new pump? Also, have you seen a tire gauge that fits this stem type?: These are definately called presta valves. I just bought a trek 6000 MTB and they have the same deal. be careful when you're pumping them using a hand pump as the valve can seperate from the tube causing a very annoying deflation. I'm yet to work out the best way to avoid this (happened to me again this morning), so it's worth carrying a spare tube just in case.

Q:Specify eight technical requirements that you would consider important, when deciding upon a particular control valve?: 1] I assume that by control valve you mean a variable orifice valve, not an on/off valve. 2] An answerer to your other question listed Metallurgy, temperature, pressure and shutoff requirement To which I note that if you need a tight shutoff you should not trust a control valve to do that, but should add an on/off valve in series. Also, metallurgy covers corrosion requirements but not obviously so 3] To which I add: flow rate [or Cv] and pressure drop fail open or fail closed response time signal input [3-15 psi, 4-20 mA, 1-5V, etc] connections [ie, fitting type] packed vs sealed might need to look at hard seat materials and/or replaceable seats, to control erosion reliability, ease of maintenance, availability of spares, timing on that vendor permanence [ie, are they entering bankruptcy ?] Cost

Q:Is it hereditary? My dad had a bicuspid valve and we got told it was hereditary but some doctors say it's not, my parents wanted to get me tested in case i had it so we would know in advance but the doctors here refuse to do it (I live in England if that makes a difference) my dad said he would pay to go private if it's hereditary. I know someone who had a bicuspid valve and 3 out of her 4 children inherited it, i know it's pretty harmless until i reach an older age but my parents and i would like to know now, i'm 13 by the way.=]: Yes, some studies have found Bicuspid aortic valve to be hereditary. Some studies show that the incidence of bicuspid aortic valve can be as high as 5% in families affected with the valve issues. In the UK there is no routine screening for people with relatives who have BAV. If you develop any symptoms or problems then of course see your GP again.

Q:i have a 1991 rm125 and i want to open the power valves myself can anyone tell me how to do thisTHANKS!: They open different amounts at different RPM ranges. Opening them all the way would cause the engine to have zero power until the engine is reving wide open.

Q:I have an above ground water pump. there is good pressure(40), but the pump does not stop. Pump co did diagnostic test and said that foot valve needs to be replaced. The company charge me $399 for diagnostic test and and about $2200 for the foot valve replacement. It is reasonable.: Yes, considering they have to pull all the pipe in the well to get to the foot valve which is at the bottom of the well.

Q:2004 R6. Runs really well... never had a problem. Has 24K miles on it. Yamaha calls for them to get readjusted at the 26,600 mile mark. So I have a few thousand more and then I'm gunna have them adjusted.I can already hear them tick especially at idle because when riding, my exhaust is so loud and all you can hear is that and the wind. Anyway, this time will come up before I know it.Just curious... what happens if the valves remain loose? Will it affect performance? How do you they become loose and is it ok to ride a bike with them like that... atleast until the specific mileage when they are supposed to be adjustd?: could cause excessive crank case pressure if the duration is way off, i know from experience. Short valve duration=blow by because exhaust gasses have less time to escape the cylinder. Could potentially cause leaks due to blow by gasses
