Q:how do i adjust the valve lash my book sys to torque to 136 in lbs but my wrench is only in ft lbs: Valve Lash

Q:And' the valve leaks......Can the valve be unscrewed from the tank for replacement? Or can the valve be serviced with a new gasket perhaps?: i would not worry about replacing the wsher inside the valve...U can go to about any home improvement store and just buy a new valve for around $10...so if they have a quarter turn valve...those will serve u best in the future plus it is a ball valve which doesnt use a washer but a ball inside turn so it is a better seal...just drain the water heater then unscrew the old one and put pipe sealant on the thread of the new one and just screw it back in and fill ur water heater back up and ur done..

Q:where is the heater control valve on a 1996 volkswagen passat: There is no Heater Control Valve. Coolant circulates through the heater core continuously. Air flow is directed through the heater core/ac evaporator in the air distribution box under the dash as required by user input. If you have no heat, there are a couple of things that could be wrong. A bad water pump, plugged up heater core, bad blend door/cable, bad Climatronic control head, or a bad actuator/motor. So, what's your question? What is the car doing/not doing that you think it should/should not do?

Q:i would like to hear from anyone who has actually had the work done. i also would like to know if the valve worked.: A backwater valve is basically a check valve that lets water flow in one direction only, away fom your system, and prohibits any other accumulation from entering into your system, like flood water etc. Yes they work very well unless they get full of junk and stuck open. You can install it yourself on the sewage line, they are about 50 bucks, its simple

Q:I was told my 1995 chevy needs an idle air control valve. I know my idle is getting rougher so I may need this. What is the function of this valve and what would happen if I don't get it? Will a new valve smooth my idle? Anyone know if this valve is hard to install or not?: The IAC (Idle Air Control Valve) controls the amount of air getting into the throttle body/intake to coincide with the correct amount of fuel to get the perfect fuel/air mixture for proper combustion. Too much or too little air will affect the performance of the engine at idle. If you have the 5.7 350 v8 the idle air control valve is really an easy fix. it sits right in the throttle body and is easy to get to. Autozone in Houston, TX has them for about $22... If you don't get it your idle will be poor and the engine could possible stall at idle.

Q:Need some info. Ok, four valves per cylinder is better than two valves per cylinder. Fine, why did Ford REVERT to only 3 valves (my guess is to save cost SOHC)? Audi and VW are using five valves per cylinder on some cars, does this offer any advantage over a four valve engine? Maserati even experimented with a six valve per cylinder!!!! (see link) http://www.maserati-alfieri .uk/alfier... but abandoned it (my guess is cost again?) Why are we stuck at four valves or would more valves actually render more horsepower? Pop some ideas best answer to reasonable answer...: Think of an engine as an air pump - obviously, we want the least amount of restriction for the incoming air and also the least amount for exhausting the compressed air. The ideal situation would be to remove the head during the intake stroke and put it back on during the compression stroke, but, obviously, this isn't possible. On a naturally aspirated engine, the intake is the most critical because the air is moved only by a relatively small difference in pressures. The exhaust stroke, on the other hand, is aided greatly by the super heated temperature and rapid expansion of the gasses. Two intake and one exhaust valve seems to be the most practical and efficient solution - adding more vales means smaller valves and an increase in the overall complexity. I seriously doubt that Maserati ever abandoned ANY automotive idea due to cost restraints. It's far more likely that adding more valves than three or four simply resulted in diminishing returns. Sometimes the allure of a new buzz phrase is nothing more than a marketing ploy - a 16 valve, DOHC, four cylinder engine, for example, is a pretty impressive resume for an engine, regardless of whether it actually is the optimum performance set up or not.

Q:I am modelling the production of phthalic annhydride and my process has a lot of FIC, LIC, PIC notations in circles on the connections. Moreover there are what i think are temprature and pressure notations in a square and a triangle. But most primarily what does a pneumatic valve do?: pneumatic valve is nothing but a valve which is operated with the help of high pressure compressed air. the can be thought of as an alternative of a metal spring... These could retract valves more quickly and reduce the possibility of piston-valve interference as long as pressure could be maintained. Additionally, the amount of seat tension required to keep a coil sprung valve under control results in greater peak lift loading, with added stress to the entire valvetrain as a result.

Q:I want to reduce the prssure of a liquid flow (ethanol) from 16.7 atm to 1.2 atm? Do I need more than one valve?: One control valve can reduce pressure, as long as there is always a significant flow through it. The main reason for using more than one valve is usually to reduce or prevent cavitation caused by a large pressure change through a given valve. Ethanol has a pretty high vapor pressure, so cavitation might be a problem. Control valve manufacturers usually provide design guides for their valve trim choices (often in software form) that lead you through the choices and requirements. Each valve design has different limits. But, my seat of the pants feel is that you can do this with one valve. I have included an example. I am not specifically recommending this company. -- Regards, John Popelish

Q:Recently, my best friend told me that he has tricuspid valve disease. So basically, the tricuspid valve in his heart is leaky and doesn't close tightly, allowing the blood to flow backwards.I just have a few questions about it and i don't wanna ask him because he doesn't like talking about his condition and i don't wanna make him uncomfortable. I just wanna know, is there any risk on his life or will he be able to live his life normally?Also, he doesn't take good care of himself at all. He completely ignores his condition. So i need to know, what should he avoid doing? Maybe I can prevent him from doing all the things that could hurt him. Most of all, i wanna know if there is anything I can do to help him.Guys if there's anything you can tell me, then please do. He's like my brother, we've been best friends since 1st grade and now we're both 16. I just want him to be okay.: Tricuspid valve disease refers to abnormal function of the tricuspid valve. Two types of tricuspid disease include: Tricuspid regurgitation - the valve is leaky or doesn't close tight enough, causing blood to leak backwards across the valve Tricuspid stenosis - the valve leaflets are stiff and do not open widely enough, causing a restriction in the forward flow of blood. Your physician may refer to this as an increased pressure gradient across the valve, found by echocardiogram or cardiac catheterization. How is it treated? Medical Management Your doctor will want to monitor the progress of your valve disease with regular appointments. They may be spaced once a year or more often, if your doctor feels you need to be followed more closely. Your appointment will include a medical exam. Diagnostic studies may be repeated at regular intervals. Your physician may prescribe medications to treat your symptoms. These medications may include drugs to treat heart failure or medications to control irregular heart rhythms. Lanyard and template handle assists with placement of ring Surgical Management Tricuspid Valve Repair When valve disease is severe, it may be necessary to repair or replace the diseased valve. Tricuspid valve repair using an annuloplasty ring is the preferred surgical approach for tricuspid regurgitation and may be performed for primary tricuspid disease or for combined cases with other valve surgery (mitral, aortic). See illustrations to the right. For more information and to view actual surgery, see: Movie: Edwards MC 3Tricuspid Annuloplasty* NOTE: Son, these patients are depressed, so they avoid discussing their condition.So the best way keep them happy as if nothing is wrong with them.OK Hope it helped you out.

Q:Why do we use in chilled water pipe network utilizing 2 way valves on all terminals except the last terminal we use a 3 way valve, also another question what does a pump shutt off pressure means: A 3 way valve has water continuously going either to the cooling coil or back to the return loop. This keeps a constant flow of chilled water available in the entire system for the coils to have chilled water immediately, when called for. Without the 3 way valve, chilled water would absorb heat while sitting the lines waiting to be used. Pump shut off pressure can mean the pressure for operating a switch on a water main so the line can not be over pressurized.
